That claim isn’t true. The book goes into details like this and taxes would go down for ~97% of parcels. It would go up a lot for parking lots in city centers and certain segments of commercial real estate.

Taxes never really go down. That's always the ploy - say the tax is a limited time, or only a specific low rate, then extend it. In this case, the people in power can play with the tax rates, but even more so in the zoning. An added avenue of getting screwed is not very appealing when taxes are already high. Let's not forget rhat if the goal is to utilize more space, that means more infrastructure and services costs. If we actually make a big impact on the space front, those infrastructure costs will go up and require substantially more revenue. I'm skeptical of the claim that most taxes will go down.

So limiting Georgism LVT to only commercial real estate would get you all of the benefit without affecting residential properties?

Then simply enact that, and the voters won't care because their taxes will stay the same (they probably will never actually decrease).

That isn't quite what I said, but I really suggest Lars's book, if you have a genuine interest in this!

You won't get an absolutely black and white one sentence solution from it, but it is thought-provoking and contains some really useful ideas, IMO.

On the contrary, that's exactly what most cities need in order for property prices to drop from insane to less insane.

LVT would exclusively take from people and corporations who own land. This in turn will allow more people to own their home.
