So in AnCapistan, instead of a Public Works Department, you have customer service? Microsoft and Cisco would own the world, and you want their customer support to take the place of government?
What's the difference between a monolithic state and a megacorporation? I'm failing to see any functional difference between the American Democratic Republic and AnCapistan (both at their theoretical best.) It's what happens when they're not at their best that I have a beef with. In America, the system is correctable, and even massive abuses have ways of being mitigated, reversed, or fixed.
I think a core set of laws is necessary for regulating commerce, and unifying military, national, and international infrastructure. Corruption isn't going to go away. If anything, it will get worse, because whistleblowing suddenly become a matter of corporate security.
You have a silly little game of socioeconomic brinksmanship with private armies involved. That can't possibly end well. That essentially means whoever can snap up the most resources the fastest wins. It has nothing to do with human rights and dignity as a human being. It encourages cheating and stealing and lying, looking out for number one, imposing your will on others by any means necessary.
In AnCapistan, I guarantee I'm going to destroy you before you have a chance to hurt me. I'm not going to wait for you to make the first move, because maximizing my long term well being means establishing and enforcing whatever set of rules I deem optimal. (I being myself and whoever goes along with me.) I'm going to seize all available resources, and you will have no recourse except to get out of Dodge, because I'm not going to acknowledge your attempts to bring to me to court at some McJudge outlet. I'm going to treat with like minded individuals, those who are able to capitalize on the sudden lack of a central legal system, and we're going to be benevolent dictators. We're going to get away with it because our mercenaries are paid, trained, equipped, and indoctrinated better than your freedom fighters.
An empire will arise out of the ashes of AnCapistan, because humans are stupid, greedy, evil bastards.
Why not impose a central state designed to mitigate the greedy, evil tendencies and maximize freedoms? A Democractic Republic seems like a pretty good system to me.
