> The lesson here is that in situations where you have a clear public good that (almost) everyone needs and consumes, like roads and infrastructure, it's better for (almost) everyone if the government simply pays for it out of the general fund and doesn't try to nickle-and-dime the populace to tax "usage".

Why is that the lesson? That's not obvious to me at all.

Taxing roads can still have a worthwhile steering effect, can be used to even cost as local tax payers are not necessarily the main beneficiaries of the roads, or can make large infrastructure projects like tunnels or giant bridges worthwhile.

Obviously, there's also arguments for free access.
