A Question about LVT

I was discussing these issues with a friend and it seems to me that any system like this would be killed by the wasteful slobs living in the sprawl because it would make their mortgage X times or more the actual property value at the stroke of a pen.

In the U.S.A., they would probably call it "unamerican". Those stakeholders with vast quantities of valuable idle land would give the same answer Bill Gates likes to give when competitors want to get a clean description of how to interface with Windows over the network: "That would be a massive and unfair transfer of wealth which amounts to an expropriation of private property".

How do you sell something like this -- the same way they sold slavery abolishment in the southern United States? Or is there a way to implement some of these ideas slowly and nonviolently?

Thanks.
