I don't feel like reading / listening through three external links, considering not many people are doing it either. All I will say is that Anarchy makes no sense on a mass scale, and most people who are Anarchists just (seem to me, anyway) don't like the social contract theory of giving up their freedom for some degree of safety. Naturally there are other kinds of anarchists too.

A story about Canada:

A town / small city in Quebec once had their entire police force go on strike. The strike started early in the morning.

- By 11am 2 banks were robbed
- By noonish there was massive looting
- By the end of the day the national guard had to be dispatched

Something like that. If you define Anarchy as the absence of controlling agent like the police, people will form groups (because as stated, humans by themselves are pretty weak) and the strongest groups will rule.

If that's your idea of a 'functioning society', all the power to you. I don't like anarchy.
