I think it'll happen the other way around. Will get out there at least in some amount because the materials out there and we can mine them. There will be plenty of opportunity in space for people to form their own societies. They'll have to it'll be too difficult to administer from earth not unless we invent faster than light travel and then you'll just do the same thing on a larger scale.

The problem earth has is there's not enough room for everyone to experiment with different societies.

With more room we have more people and with more people we have more innovation eventually someone will invent the replicator or matter synthesis or something and we can stop worrying about resources at which point governments rather cease to have any power.
