While I understand ideological differences between ancaps and anarchists, I don’t see how these ideologies differ in terms of practical mechanics. Both advocate for ad hoc best effort structures that are flat and decentralized. Both groups want central governance abolished, but fail to explain how that would be accomplished in concrete terms.

In each case it seems like there’s an underlying assumption that the only thing stopping majority of people from subscribing to the given ideology is the fact that the state exists. Seems to me that even in a situation where the state did collapse, what would happen in practice is that groups that favor central organization would simply rise to prominence out of the resulting chaos.
