Put another way, we collect PLENTY of money already to pay for the roads. I'm all for FULL privatization of operations with ZERO government access to monies and ZERO access to data on the movement of private citizens. And it's certainly reasonable to ask what POSSIBLE PATHS exist toward privatization and fee-for-service. Perhaps the author is correct on that. But this one is tricky. Much of the tolling that has been proposed recently is nothing more than a tax increase. That doesn't mean more tolling isn't a good idea in principle, but the devil is in the details.
