Any good LVT in my mind would robustly employ "conservation easements", which lower/waive taxes on land that is preserved for environmental protection. These are a common tool of land trusts today, and IMO they would fit great alongside LVT.
It's taxed now as well (in almost all jurisdictions). It's just also taxed on any buildings that sit on top of it (that latter portion of which provides a disincentive to development).
Understood, although not much of a disincentive. I think I have an aversion to just taxing what people own. When it's a building, at least that is related to services they're likely to consume; it's not just "we want a cut".
