I suspect the general idea is that either it'll be voted in, or (more likely) the current system evolves that direction.
If there's to be any chance of a successful transition, I suspect it'll need to go the evolution route. For anarchy to be viable it takes more than just a political change, it requires a whole new mindset. A mindset I don't think is possible for humanity, but if that's true, a political system will never evolve that far anyway.
