Everybody likes to imply that Elon is going to make some sort of shit new society in space. Perhaps they'll get as far as trying, but the odds of it working out are questionable on social grounds alone.

In general, people living in hostile environments develop higher levels of trust and social responsibility. When you live closely with people, where everyone's choices impact everyone else, when a single person intentionally screwing things up could doom the entire community, you get societies that are pretty much the polar opposite of the archetypal billionaire libertarian vision.
