The trouble I see with this is that authorities naturally arise everywhere. No place on Earth has zero authorities. An anarchist (seems to me) is therefore always in a position of effectively being under the rule of some authority that they reject, while lamenting that other people are "dumb statists".

Myself, I believe that something like a state will inevitably form (if a state does not form locally for a while, the territory will just be overtaken by a larger and more remote state, which is likely worse). Therefore the sensible approach is to design the state in such a way that its power over citizens is kept in check, to avoid tyranny. This requires constant vigilance of course.

Happy to learn more about your point of view on this.
