I said that the answer lies with a new left because the radical left has historically always dreamed of the dissolution of state power and a move towards a cooperative international community directed by "the people" (which in the 21st century could be a type of distributed governance).

I can see that. However, I think it can be argued that the mantle has been largely assumed by the libertarians. I do not see communism as aligned with decentralization, although there are overlaps. Whereas communism charges the governance structure with the task of public good, libertarians tend to argue that the public good ought to be a byproduct of a system. There is a lot of shared ground, yet I think libertarians are more closely aligned with what technology is making possible, at least in the short term. But, really, what I am arguing, is that we needn't look to the left or to the right. Because they are reflections of a system that is becoming unstable. IMHO we are seeing left/right political dissonance because those views don't reflect the possibilities of a new framework.
