Georgism[1], which I'm fascinated by. One way to organise it is to ask people how much tax they're willing to pay, from which the land value can be derived (as that's the real point of assessing land value for someone who isn't willing to sell that's the real order of things). However, if someone bids on the land for that price you must sell.
> Are there any good examples of governments that use LVT in practice?
I thought there were only one or two places using LVT but it appears there are quite a few[2], but it's rarely pure LVT.
