There have already been many experiments in anarchy. They are usually not widely known, probably because the powers that be don't want people to be getting too many ideas. Most experiments get crushed by state power and don't last long.
Some famous examples include:
- Rojava Kurdistan in Northern Syria. This is a region of several autonomous communities, together comprising several million people, all self-determined but federated together with common values. Technically not anarchist but "Democratic Confederalist" - a new ideology proposed by former Marxist leader of Kurdish Worker's Party, Ocalan, who was inspired by anarchist Murray Bookchin. These are the guys with the female YPJ military that were kicking ISIS ass. This region is under heavy threat from Turkey and others and the international community refuses to recognise it, making trade difficult.
- Christiania in Copenhagen. This one is still going and has made deals with the state that result in some compromise but allowed them to maintain their autonomy. There are many similar squats/communes to this across Europe.
- Parts of Chiapas, Mexico. Somewhat under autonomous control by the Zapatistas
- Catalonia during the Spanish civil war. Taken advantage of by other socialists and the USSR and ultimately crushed by Franco.
- Ukraine Free Territory during the early stages of the Russian revolution. Eventually taken over by the soviets.
None of these situations needed rescuing from UN forces. It's usually the same people who make up the UN that are actually the ones that cause their experiment to fail.
Democracy is too optimistic for some parts in the world as well. No system such as (Autocracy/Democracy/AnCap) can work without certain level of cooperation from everyone involved. True AnCap requires most and never-seen-before amount of cooperation but if possible, it does give/predict awesome results.
Maybe they'll become more realistic once we've either evolved or augmented ourselves to a much higher level of intelligence and conscience.
Some of us already have :).
What do you mean by that?
Not quite there ofcourse but they are getting there:
Not all forms of anarchism subscribe to this.
I would even like to see a few thousand anarchists start their own society and try to put their theories into practice on an artificial island or something. Even if they all need to be rescued by UN forces at the end of the day, the experiment will provide the rest of humanity with valuable insights that philosophers and anthropologists can grapple with for decades to come.
For my taste, though, both anarchism and libertarianism seem to be based on an overly optimistic view of human nature. Maybe they'll become more realistic once we've either evolved or augmented ourselves to a much higher level of intelligence and conscience.
