Some people argue no compensation is required but I think in reality an LVT at 100% reduces the price of all land to $0. Given that land is substantial portion of retirement savings in our current economy, completely obliterating land prices without any compensation seems morally dubious. Perhaps if you do it slowly enough that you give everyone time to adjust and make the market adjustments gradual enough that people who need to sell land for retirement can still get something like 90% of the value initially it could work.
