Problem is, we had these kinds of societies in the past, and they mostly got taken over and incorporated into societies with hierarchal structures, because those had militaries and were aggressive. Maybe I'm overstating that a little bit, but there was still plenty of conquest, and I don't see how a return to decentralized communities prevents that from playing out again. Or alternatively, stops some communities from being raiders and pirates, and the eventual desire to have a stronger response that a hierarchy can bring to bear. At any rate, the current global order is very far from anarchy, and it's extremely difficult to see how it could be come about in part of the world without being taken over by countries with imperialistic ambitions. Imagine what Russia and China would do if somehow Europe and the US became anarchistic.
