a libertarian country would be 100% toll roads
Uh, every road in America is a toll road. Have you ever heard about gasoline taxes? Does pre-paying your road fees at the pump make you happier for some reason (would love to hear what that reason could be) than paying the fees as you use the roads (ala EZPass et. al. - let's assume you can use them anonymously).
The difference is that now the gas taxes are not all spent on the roads (they get diverted to police pensions and political cronies' boondoggles) and the money that is spent on the roads does not go through a true competitive bidding process (again with the cronies), making the costs higher and quality lower than they ought to be.
I abandoned that stupid philosophy that day.
It sounds like you did so without understanding how roads are paid for. Look, it's hard to know how everything works, but the more people do know how things work the more likely they are to be libertarians. Because people suck, especially those who seek power.
I don't want to live in an ideologically pure world; I want to live in a good world, and libertarianism wouldn't lead to a good world.
It's an ideologically-driven stance to accept more expensive, lower quality roads and political corruption and waste for the sake of a particular revenue model. Also one that necessarily supports a worse world.
