Apologies. Misposted as AC. I totally agree with your sentiments. My quibble is that your definition states what may be a necessity, but it is insufficient and IMO cannot stand alone as an objective definition. That is a pity, because a terse definition would be useful.
Are you sure about that? How much more energy is it going to take to make these? If it's more, then where is that energy coming from? Are the raw materials heavier to transport than the current ones? What waste by-products are produced in doing this? What can be done with those by-products?
I would like to see authoritative comment on the overall origin-to-disposal/degradation atmospheric carbon budget of biomass-based vs petroleum-based PET. The energy budget is related, but mainly as it affects atmospheric CO2.
Superficially, the burial of biomass-based non-biodegradable plastic looks rather like atmospheric carbon capture and sequestration. An environmental plus. Biodegradability is a two-edged sword. It removes junk from the environment at the expense of releasing carbon to the atmosphere.
Parent is right, you need ALL of the figures before making a judgment. Maybe I missed a trick.
Deja Vu all over again. "Many users fondly remember the LEO III and enthuse about some of its quirkier features, such as having a loudspeaker connected to the central processor which enabled operators to tell if a program was looping by the distinctive sound it made." http://en.wikipedia.org/wiki/LEO_computer
The definition of extreme depends on where you stand. Life emerged on earth in what we would now consider an extreme extraterrestrial environment, with an ammonia, methane, hydrogen, carbon dioxide atmosphere. Temperature uncertain, but probably high. Probably also pretty dark at the surface. Think low temperature Venus.
Once the mechanisms of life were up and running, they could evolve to withstand virulent poisons such as oxygen. Free oxygen is a result of, not a prerequisite for, life.

One thing they are really handy for is wiping the platters.

The camel endorses your viewpoint.
I don't think they chose a very good camera angle for showing off the concept.
Agreed. The wing and tailplane look to be a continuous loop, too, which is not immediately obvious (to me, anyway)
Says it all, no?

What they can't do is get another ID card with a numerical identifier on it that already exists on your card.
Is that achievable?
If so, how?
