Ok then you need absolutely no rule, a free currency of course, like btc.
And how do you protect citizens? I mean what would prevent a company like Google to just hire some mercenaries and kill the potential competitors as there is no police and no government?
Who said no police? You can still have police run privately like a corporation.
Basic policing like keeping the streets clean and emergency 911 calls can be easily done (and possibly more efficiently) than government police.
You know in Japan the subway system has a maximum 1 minute delay and its run by private corps.
When I was last time in government subway they always have a 10-15 minute delay.
So you have to admit that private stuff is managed better, and when you call the cops because there is somebody in your house, then its a matter of life and death if they delay 15 minutes because they forgot to buy their donuts.And for personal protection, there are always security guards and security services available, you just cant afford it currently, but with low or no taxes I guarantee you it would be as cheap as buying a hamburger.
There's a slight difference between someone offering transport and someone offering violence. It's very difficult to control violence without a monopoly.
