The worst part is; could you imagine a toll collector serving the principle of self interest? They would operate on a simple equation to maximize profit based on the number of people who agree to pay the toll weighed against the number who decide it's too much and turn around. It would have NOTHING to do with road maintenance and upkeep. Next to nothing would go back into the road, but instead, it would go towards muscle, towards hired goons to control the road in which they're charging WAY to much for. It's still all just force. It would be a NIGHTMARE, and something worth starting a war over.
The whole Anarchy thing collapses under the weight of roads, because it's very hard to pretend that the world is filled with good people once you start envisioning a world filled with toll collectors.
As far as a Gas tax, we're right back at taxes again, government, force, and we're throwing in a middle man who'll either need to be paid or forced. I say local government, bottom up ownership operating in the light of day, accountable to a budget and the people they represent.
