Im not a full on anarcho capitalist.
I am a deontological libertarian.
I am also a minarchist libertarian.
To me, the quasi marketisation of what are essentially the pillars of civilisation (the military, the police, an independent judiciary) is retarded. These institutions are better served by the englightened ideals that put limited government into the constitution, and a bill of individual rights in the independent judiciary than some kind of bullshit market.
After all, these government monopolies obviously emerged from a state of anarchy in the state of nature, so i don't see how reverting back to that is somehow more free.
