This is false, LVT only cares about the hypothetical economic value not the actual economic value.
Let’s say you buy some farms in the middle of nowhere for 10k/acre and put a theme park on it. Your LVT taxes are in theory unchanged, though depending on how it’s calculated the value of land around that property increases because it’s near a theme park. Then your LVT increases when people start to build hotels etc around your property.
What’s interesting about this model is your incentivized to develop land as a single unit. A sports stadium with associated shops and hotels is valued as if none of it was there, but split it up and each pays more due to proximity to other businesses.
And of course what improvements are included or excluded is rather arbitrary. Do you value a natural or artificial pond differently?
