I'm not #anarchist but for what I learned so far through social media, #anarchism seems like something possible in small communities like towns, villages, city states etc and hard to accomplish on higher scale like big countries. I mean, not saying I know everything about it, it could just be my lack of knowledge.
@introvertcatto I think you are right, and IMO its also not going to be able to fight off any large industrialised state invading them.
