I'm inclined to think that thinking of anarchy as a concept by itself doesn't make sense. The concept of Anarchy is in the same bracket as the concept of "State". A state can be a state+monarchy, state+republic, state+democracy and so on. But you don't get a State by itself as some kind of platonic ideal or something.Crypto+anarchy. Anarco+communim, Anarco+capitalism make sense, those are systems you can take practical steps to build. Whether they'll work or not is the issue. I think we've seen a slow but certain shift from hierarchical systems to networked systems over a few centuries.What I'd ask SS and northsouth and PurpleHue, is what is their vision of the future, say in 2050 and in 2100.
