Your interpretation of freedom is pretty radical, and not in keeping with American tradition, IMO. I couldn't disagree more strongly...travel restriction and monitoring is characteristic of the worst kinds of totalitarian governments.
I think you are trying to say that the use of highways is not free, which is true. But there is no legitimate relationship between paying for highways and being tracked like animals by government bureaucrats.
My point is that highways are not a natural freedom, they are the result of other people's time and money and their unfettered use shouldn't be taken as a right - because that is where someone else's obligation begins.
I think government tracking for surveillance purposes is an unreasonable fetter, and hope enough people agree it would not become reality. But I would have no problem with the economics a pay by usage system - but I suppose that in reality that is inseperable from the surveillance aspect.
