If you look at the word "arch", it means, sort of, support structure. ἄρχω, "beginning", also "authority" (story from beginning to end). Bitcoin, often associated with the absenc is for example, obviously, analogous to how "-archy" has been used. It is an authority, just not a human one, and because it is not a human it does not have instincts that humans have, like, dominance behaviour.
I like the word "paxarchy", non-coercive rule systems. To me that is what most people mean with "anarchy", they use it equivalent to "voluntaryism".
