Oh boy I love how the Freetown Christiania is first on that list. Since that’s a place I actually know very well.

You list is bullshit, that’s like saying 5 friends are an anarchist society. Those are NOT self governing societies. They are under the rules of countries.
If any are not, they are probably just very small cult like communities.

They do not run factories power-plants, electricity grids, infrastructure or anything of any serious scale, and are in no way models for how to run a country.

Freetown Christiania had lots of problems with crime, and they also had huge problem of elitism as in very few people actually decided everything, the power structure is/was very much based on who had lived there from the beginning.

All this anarchy idealism/ideology is bullshit that doesn’t work in real self governing societies. Of course it can work for small groups, like what the fuck, just because I live in a street where we help each other, we don’t form a government and police for that!

Christiana may have called themselves autonomous, but they never where in any meaningful sense of the word. And the truth is they needed help from criminal rocker gangs to get rid of widespread sales of hard drugs. And later they chose to legalize according to Danish law, and called on help from the real police to get rid of the remaining drug sales. Christiana today a mostly normal part of Copenhagen today, but maybe still influenced more than average by the 70’s flower power roots, although there was never any flower power in the way that society was run.
Christiania was always 100% depending on the normal society they existed within, the dependence wasn’t superficial either but for EVERYTHING, Jobs, hospitals, doctors, sewage, electricity, It’s little more than a football club deciding to play by their own rules. Yes they can do that, but they still live in a society governed by rules on everything else.

I’m sorry, but your dream is an impossible lie.
