Taxing land will not create more housing; if it was profitable it would happen regardless of tax.

It absolutely goes away. The only value of land is its utility to humans - the infrastructure, buildings, utilities. Just look at all the ghost towns that lost their economic viability. That land now has negative value since old buildings need to be demolished before being developed. Measured in acreage, there is effectively infinite land, but without infrastructure and buildings it has no value to people.
The value of land that is polluted and needs to be rehabilitated becomes negative.
