One could write a book, but simply put, an anarchist community wouldn’t work if its members were forced into it. For example, if a nation’s government collapses, there would be chaos. Anyone whose “comfort zone” is stripped of him would freak out and possibly be violent. That’s where I think the misconception of anarchy comes from.
But, if a community’s members willingly took part in an anarchist lifestyle, it could be great. If the US allowed anarchist communities to live in its country, then anarchists and democracy could live side by side. Anarchists wouldn’t give or take anything from the US government- that means they wouldn’t pay taxes or vote, but they also couldn’t take part in any welfare or other government run programs. That way, American citizens could have a choice of how they wanted to live. Democracy or anarchism. Nobody is forcing anyone to do anything, so nobody can blame anyone else for his/her problems. But I hear that’s crazy talk. ;)
