I think it's funny how every LVT discussion eventually comes back to some inclusion of other factors to adjust the taxes or provide exemptions, which starts to defeat the claimed purpose of a Land Value Tax.
LVT is a concept that sounds amazing and novel in a vacuum, but starts to look less ideal in the real world. The people who think about it enough start to include factors like structure value and different exceptions for how the land is being used, which starts to look a lot like existing tax code in most places.
