There’s the state neighbouring anarchists who can’t form a state and so probably anarchists exist protected within the borders of some state unless some state respects not a state
However a state cannot acknowledge existence of something that doesn’t exist and has no joint body of commonality. Hence genghis khan moment. A state conquers the ownerless land.
Thus emergents from this Darwinian history are states. Squashing individuality in name of security against genghis khans.
Anarchism remains a purely theoretical thought exercise or a relic of the far past tribes
Good luck being efficient and quick without central command and centralised power. There’s a reason anarchism didn’t survive evolutionary process.
Our economic systems and governing method are direct outcome of evolution. If they will be unfit for the contemporary reality they will die as all things do in nature that we are part of. Strongest and most resilient emerge. So far it’s been liberal democracy but there’s nothing that says this is a permanent victor
