How would there be guarantee that their neighbours won't attack them? Even this is a problem for Chéran, hence why they have armed patrols. Heck, even practically speaking, we are already living in an anarchy. What are nation states if not self-organising society? Even with attempts of international cooperations through globalisation, that still failed because each countries' cultures are too distinct from one another to create a mutual trust.

For ideal anarchism to work, there has to be a global cultural shift for humans to be like minded enough that mutual trust is built amongst each other not to attack or cheat each other. The only instance I have seen this work is in fiction in Dune, where the planet Arakkis is populated by Fremen and living in anarchist framework with their different tribes and little cultures, but overall identify themselves as Fremen and have solidarity against invaders. Although, that's where their problem lies, outside the planet. Even utopian anarchism has to extend into universal scale.

Place barriers at the intersections. Not a member, not allowed in.

Thanks, I'll check it out.

Edit: this is very cool, thank you. Some takeaways were that there seemed to be a strong solidarity and vision among the community of how they wanted things to be run. So that may be a first step to building such organizations. The second is that the government officially tolerates their autonomy which is interesting. This may be more difficult in the fascist USA where I'm located.

Unfortunately, I think to get off the ground and begin building community buy-in, such an organization would need to avoid actions that would cause them to be immediately shut down and brutalized by our governments. This will limit the available tactics significantly.

Have they? I've heard a little about a resurgence but I also was under the impression they had sort of collapsed decades ago.
