On one hand it is incredibly funny that after such question only two books and one movie got mentioned by title in thread and two of which are a work of fiction, but then again, LeGuin is still better than Proudhon lol.

On the other hand, this anarchist society in Disposessed is a pretty good analogy in how it is essentially entirely on the mercy of the people on the Urras. Even the anarchist utopia is vulnerable. Also for some weird reason Anarres seems to represent USSR since it existence means states on Urras are giving workers some rights, analogically to Western Europe building social nets.
