One of the problems with going off and doing it in some other place is that typically such experiments have been crushed by outside force. Especially if it began to spread and threaten the status quo, I think they would send in the armies pretty quickly, or just use drones.

And the state itself is incapable of reforming itself into a vehicle for our liberation. They tried this in the USSR and while some good things happened, it fell well short of anything of the sort... Even though the intention in creating state socialism was to bring about the withering of the state and the emergence of a truly egalitarian society.
