There’s nothing stupid about paying road use taxes. Money to maintain roads has to come from somewhere, that’s a pretty basic government function. If you’re not paying it in gas tax, paying a road maintenance tax in another way is completely reasonable, even to conservatives, or should be.
Or do you expect them to get this benefit “for free”?
There are legitimate purposes for government and illegitimate purposes. Most of the federal and state governments activities are illegitimate - mostly increasing taxes and growing government to line their own pockets.
“Greed” isn’t as nearly a problem in the free market as it is in government.
On the surface, this actually sounds reasonable and proper. The problem is, money is fungible. The powers that be area constantly appropriating the money intended for roads and infrastructure to other purposes. All the money goes into one big pot, and is doled out as desired by politicians. If there were some way to guarantee that the revenues from gas and similar taxes was actually used for infrastructure, I'd agree with you 100%. Unfortunately, the reality is that in most states only a fraction of gas revenue actually supports infrastructure spending.
