Anarchy would never ever ever work. Human nature is not anarchical but hierarchical.
Hmm, haven't relatively large anarchic communities already existed? For example, those in the regions of Catalonia and Aragon in Spain, 1936.
and how long did they last? just a blip on the map. i don't know what the solution, but if you have an anarchistic society, you're probably not going to be as well-organized as government run states.. which means they will come for your ass and use you and your resources up. it's just an extremist, one-size-fits-all ideology that is just wishful thinking to me.,
