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.
Yes, unfortunately, this would be the most likely outcome.
I wouldn't be so sure. I think it's important not to force the ideals onto people and promise to give them power later. Instead, give them the power first, and watch them all learn to wield it. The only thing is, the learning ramp is pretty steep from the point we're at right now, so it may not be so pretty to watch as people initially try to figure things out.
Actually, I think the upcoming, inevitable mass automation that the current system failed to prepare for may be an opportunity to jumpstart this process. Unfortunately, it will not be pretty either.
