No person is inherently good, evil, or anything in between. It's social norms that really determine what is good and evil, and what you interpret to be good and evil...but I guess we could start a new Nature vs. Nurture thread...though that discussion has been beaten to death.
But seriously, how would anarchy happen. I know Conservative Man has backed away from his ideal capitalist anarchy, but let's just pretend for a minute that in theory, all of his original assumptions would stand (people are inherently good, that courts would work, that no mad man would blow up the world, that money is somehow regulated)...how exactly would these socieites happen? Do people vote for it to happen? Is it enforced on a society?
The only way I could see it happening in theory is if it happened across the world all at the same time...or at least in the industrialized capatilist socieites of the world. Otherwise, if State A went it alone and dissolved into itty bitty anarchist societies, wouldn't other states, afriad of the consequences, invade the little anarchist societies, as this would be a threat to the state system? The transition into our current state system was preceded by a 30 year war in Europe which was kind of nasty.
Also, what about the psychological impact of anarchy would do to people. I mean, no more nationality (I don't think this is necessarily a bad thing), but something like that would take a little while to grow out of, as it is a part of people's identities. Humans are social creatures, and we have a psychological need to group ourselves. What would happen to our imagined communities.
How do you completely smash one set of norms which guide society and replace them almost immediately with another? Would there be a transition, and how would it work?
How complicated would it be to play Diplomacy in anarchist socieites? Could you?
