An air gap is not very useful if it needs to be crossed on a regular basis. If you write your single session CDs on a compromised network, the instructions on the CD itself can also be compromised. Also, when you make it too inconvenient for the operators to do their jobs, they'll undermine your security plan by installing a hidden access point somewhere.
If the fastener is hard enough to turn that it breaks an ABS socket, then it's going to break the wrench instead when you use a steel socket on it.
No, because the force = torque / arm, so the force increases as you get closer to the nut/screw. Try this socket for example:
http://www.vartools.com/images... It's obvious that the forces on the socket/bit are much greater than the forces on the wrench.
Who cares about your contrived example ? They're in the ISS, where everything is assembled with white gloves and torque wrenches. They're not fixing rusty old cars.
The term "minimally" is too vague. Truly minimal means zero regulation, thus allowing armed gangs to roam the streets and steal your stuff. And as soon as you add more regulation, you need laws. And laws means you have to have representatives to write the laws, and others to enforce them. And before you know it, people want more laws, and you end up where we are now. That's how we got here, you know ? Everything has been tried before.

Sending boots to the Moon is mostly engineering, a lot of money, and very little science.
We already know quite a bit about Uranus. It's big, colourful, full of gas, and has rings around it.
It's a matter of foreseeing and predicting risk, and then defending against it in a cost-effective way.
How do you know that it wasn't done properly in this case ?
Or... power down the Large Hadron Collider, and see what happens :) http://lhc-machine-outreach.we...
Send a probe to Europa, but instead of sending more men to the Moon, do a sample return mission to Mars.

Maybe this wasn't an average attack ?
Still doesn't happen more often than I might think.
In some cases, maybe. But that's hardly a practical concern because you can simply print a wrench without a ratchet if you need the extra strength.
it actually did happen, and happens more often than you might think
Not on space stations.

It's more a skimming just above the atmosphere-station.
Actually, they only printed the wrench. If you attach a metal socket, it's probably quite capable.
From the pictures in the link, it looks like the 3D printer is completely closed off and has its own air filter.
Why on earth was there even an ISS in the first place ?
But the rich will not recognize that until the mobs with pitchforks are breaking into their gated communities.
That's what armoured battle robots are for.
The purpose is just to make more money. If that can be done with worse service, we'll go there.

Instead of catching asteroids to feed your children, won't it be much easier to just let you die somewhere ?
There's only so much beach front property, you know.
There's no point in repeating your statement, when we can all read the first one again. Instead, try explaining what you mean by "free".
The poor won't be able to afford AI to work for them.
Free markets are as old the world, but people don't like it when a handful of people end up getting everything, and the rest gets nothing.
Guess what, humans are essentially the only ones who can't tell when bad weather is coming.
And we're also the only ones that can understand the weather forecast on TV.
