I'm pretty positive on this idea. Driving on roads imposes an externality on other people, why shouldn't we attempt to make drivers/companies internalize that cost by charging a toll? I'm not so positive on it that I would support it if it were clunky and imposed a big transaction cost (having to stop and pay). But if it were automatic like the tolling via camera that happens with a certain bridge near me then I would support it.

Of course it's probably low in importance compared to certain other modes of travel that have big externalities that aren't tolled/taxed appropriately...(air travel).

Toll roads are a bad example IMO. We could have an entirely separate conversation about how they hurt the most disadvantaged and are typically a gigantic scam when played out on broader timelines. If you want to see the end game on toll road experience, come visit Houston sometime.

A consumption tax would be something more like "I want to buy a new hillside estate and I have to pay this special 20% fuck you tax because I'm excessively wealthy".

Consumption tax code could be fairly complex in order to minimize impact to those who are purchasing day-to-day items and other essentials. I would happily pay extra taxes on my discretionary purchases like high-end PC hardware (and probably make more of them) if it meant that on the other hand I wouldn't be penalized just for working and making money. Anything you could buy at a grocery store should probably be exempt or in a tightly-controlled tier.

Property taxes are cool too. Land is a ~fixed resource, so you have to have some counterpressure involved there. I am not saying alter property taxes to accommodate any of this, I just think they have a place.

New Zealand funds its roads via taxes on petrol, and for non-petrol vehicles "Road User Charges" which are basically a tax on oddometer kilometers. I haven't checked if how the balance between revenue generated by these taxes compares to spending on roads, etc. though.

Roads contribute to massive negative externalities.

If every road was a toll road you would have more walkable cities. Better public transport options. Less emmisssions.

Sounds like a wonderful trade off.

Sorta, I view taxing labor as bad policy. We should not disincentivized labor. But… just saying stop this tax usually has people upset at bigger deficits. So if we tax consumption instead the end result is lower (or no) taxes for income and higher taxes on wealth (indirectly).
