    Your post outlines the reason I stopped playing EVE. Is that it is anarchy. Even staying and mining in 1.0 space, one can get ganked by a suicide mob using clones or expendable toons.

    Sir, I only suicide gank on my main. It's more exciting that way! Also, high sec. space is not safe space.

    There is even a specific day for killing mining vessels.

    "Hulkageddon" is an in-game event organised by, funded by and supported by players. It's exactly the sort of emergent gameplay that EVE's all about. A properly-run mining operation in 1.0 with decent fit barges and support ships is 100% safe from any suicide gankers. Mining in deep alliance 0.0 is also pretty much completely safe from suicide gankers. If you lose ships to Hulkageddon, you should (a) pay better attention to the news and (b) make some friends.

    I like the mining side but there is no reason to pursue it if half the mineral, and it is the most profitable half, are only available in lowsec.

    Join a corp, move to 0.0, profit! Look ma, no "???"!

    I like the industrial side, but there is no reason to pursue it if the market price for an item is less than the cost of the minerals that go in to it, let alone the cost of production.

    Train reprocessing skills, by under-priced ships, reprocess them, sell materials, profit! Look, still no "???"!

    I liked the idea of industrial and business sides of the game, but they have just become a way to get gear for PVP. Mining ships are under armed and under armored, unless one wants to give over most of the mining capabilities.

    ...join a corp, use an Orca, watch local. Or mine in a Rokh. It's a trade-off: greater income, at the expense of greater vulnerability. If you choose to fly a ship you can't afford to lose, then it's your fault when you inevitably lose it.

    Freighters are completely unarmed in a universe with no law enforcement.

    There is law enforcement; it's called CONCORD. Choose your mode of transport appropriately to your cargo. If you need to transport high-value items in high sec, use a collateralised courier contract or use the corp hangar on an Orca. If you need to transport bulk low-value items in high sec, use a freighter -- because it has ludicrous HP, suicide gankers won't attack it if they can't get enough profit to cover the ships they'll lose. If you need to transport items in low sec or 0.0, use a blockade runner and a scout (avoid transporting bulk low-value stuff around there, it's not worth it)! Since the insurance nerf, the likelihood of being suicided has gone way down, if you take basic precautions and don't AFK.

    By the way, have you ever looked into the transportation trade side of the game? I don't think I saw a single transportation job that wasn't a setup to be ganked so one would lose both one's deposit, one's freight, and one's freighter.

    "If it looks too good to be true, it probably is." Corps like Red Frog Freight are doing really well out of bulk transport, and they're always recruiting freighter pilots, so it clearly can be done.

    CCP touts the multifaceted nature of the game, but it has turned into nothing but PVP.

    When you click "Undock" you're consenting to PvP. It's what EVE's about. Even so, unless you do something blindingly stupid (like flying a cargo expanded cargo rigged officer fit Hulk during Hulkageddon, or undocking in a cyno Kestrel with 74 PLEX in the hold while wardecced), then it's dead easy to avoid PvP, and you'll never lose something you can't easily replace.

    It also makes it considerably more difficult when a launch provider like SpaceX wants to sell launch services, which is a large part of why Russian and European launch providers are currently creaming US launch providers on the international market. For example, the following difficulty occurred when SpaceX's Falcon 1 was launching a Malaysian satellite:

    http://www.hobbyspace.com/nucleus/?itemid=13078

    Technicians discovered the satellite and the Falcon 1 upper stage rocket share a nearly identical vibrational mode, which could set up a damaging resonance. SpaceX is bound by ITAR restrictions from assisting with any technical problems on the foreign-owned payload, so the company delayed the launch to add some vibration isolation equipment between the rocket's upper stage and the payload adapter.

    "The easiest thing would actually be to make some adjustment to the satellite . . . but that's not allowed," Musk says.

    Just one of many examples, sadly. Unless Congress acts promptly to introduce some sanity into the ITAR provisions, I fear that ITAR is inevitably going to drive innovative and competitive launch providers like SpaceX out of business, and prove to be the final nail in the coffin of the US space industry.

    Certainly not true. ITAR is export controlled only. Typically DoD stuff. The model being looked into will be that of procurement only. The government will no longer have any ownership of the systems. Just like government cars and trucks that are bought for every day use are assembled in Mexico/Canada from parts from China or wherever GM/Ford builds them. Oh the contract winning company may be US based, but that's where it stops. There is no protection for the workers underneath.

    Oh, sure, this is entirely correct. Maybe I should apologise for calling you an idiot, despite your hideously misinformed opinions on the constitution of the SpaceX workforce and supply chain. :-P

    But think about it this way. If you, the US taxpayer, have just spent a billion dollars on a set of instruments for use in orbit and have four of your best and brightest young people sitting on top of it, surely you'll want to make sure that you have the best performing and most reliable launcher money can buy?

    If that can be sold to you by a company based in the US and doing all of its manufacturing and assembly in the US, so much the better. After all, this is exactly the type of very high tech project that your country still prides itself on. But given that the cost of the launch is a relatively small proportion of the cost of a space mission, but contributes a very large proportion of the risk, wouldn't it be reasonable to buy flights from the best provider available, whether based in the US or not, in order to minimize the risk to the taxpayer's investment in the equipment and personnel to be launched?

    This all depends on how you perceive the US space programme. If you consider the missions to be a good in themselves (e.g. provision of high quality meteorological data, monitoring of high-altitude ash clouds from volcanos, measuring ground displacement and urban damage in the wake of an earthquake), weighing up only the results of each programme against its final budget, then you come to one conclusion. On the other hand, if you -- like several US Senators, apparently -- consider it most important that NASA is the mechanism for a large taxpayer subsidy towards jobs in the high-tech industries, then you'll come to another.

    In this case, Commercial Space means Outsourced.

The Falcon 9 is very much an American rocket built by Americans. There are indeed "no foreign nationals, no outsourced jobs."

    It's unusual to hear someone praising ITAR. ITAR is the reason that non-US organisations generally don't use US launchers for their payloads -- they can't work closely with the launch provider, particularly with respect to the sort of detailed technical information that's often very important in ensuring payload-launcher compatibility. People I've spoken to in the space industry while at conferences in the US frequently bemoan the fact that ITAR heavily restricts their hiring practices, meaning that they often miss out on being able to employ top people.

    ITAR is what's holding the US space programme back.
