If the world were made up of only ubermenchen we would not need government (my definition of anarchy, the absence of government), but given that that is not (and probably never will be) the case we must live with our regulatory creation but constantly struggle to keep it in good (democratic) condition. The popular idea of anarchy is a macho romance.
You are, of course, correct. There have been a few practical models of anarchism, like anarcho-syndacalism, but the current state of international politics and ecological emergency have pretty much made that plan, and others like it, defunct.
But by the same token, i don't imagine that you are suggesting that naively accepted authority is the solution...man, i didn't realize i had stepped into a 4-year-old thread when i originally posted.
