I’d be an anarchist, but I think anarchism would only work if the world is far more connected than we are today. Anarchist communities developed organically because their environments are close to each other, facilitating cultural exchange and then evolving into a converging culture where people in the communities eventually “think alike”. It is like with Fremens in Dune. The entire ethnic group inhabit the entire planet, but their lines of communications are pretty reliable and fast, so in that sense the world of Fremen is “small”, allowing for an organic development of an anarchist culture by themselves.
