I don't disagree, But I do think the idea that the government, not individuals, is the ultimate owner of the land is a fundamental assumption of LVT. Not all people believe this.
The basis for this assertion is that land supply is fundamentally very scarce, so this is zero-sum game. If some have too much, others have little, and the former can extract substantial economic rent from the latter.

Proper use of allodial title and homeowner's exemptions could go a long way.
