Some people seem to suggest that but I don’t.

Only calling out the problem with taking someone’s property tax and increasing it 5-10x.

If their property went up 5-10x that's a huge win for them.

But that’s not the discussion. A land value tax captures pretty much all the value of the land. So a prime spot in a major city might cost $500,000 but have annual property taxes of $100,000.

The goal is to make the land unattractive unless you optimize the use of the land and build high density.

That's right and it should be that way. The value of the land is a function of the success of the local community - it shouldn't be captured by a private investor while workers continue to pay income taxes to service and improve that land.

But if your only objection is that elderly/disabled landowners shouldn't be pressured to pay taxes many states already have laws like that in place, eg https://www.state.nj.us/treasury/taxation/ptr/
