I was an anarchist in high school too. I was an over-achieving individualist who took personal affront to the norms and rules imposed on all school kids, and people in general.
I researched anarchy philosophy and policy as it presented itself over the years. It worked for me: I felt that people could be trusted to behave correctly without the imposition of external rules and laws and the violent enforcement thereof. Obviously I was wrong. But I remain basically committed to my original ideals: an ethically motivated individual does not need to be ruled by fear and force. What, however, does that same individual do when confronted by the violent - or even not so violent but still evil - application of the rule of law?
Anarchocapitalism has some interesting answers to this question. It's not a utopian variant that believes everyone can simply be trusted not to behave badly.
