I disagree with your analysis, but putting that aside, you are ignoring the fact that LVT has been applied in the real world. Denmark, Estonia, Singapore, Taiwan...
Obviously disentangling effects is hard, but there is no evidence that suggests it has the deleterious effects you mention.
LVT: You own the land, you just have to pay these taxes on it every year or we will force you to sell it so we can collect our taxes.
Leaseshold: We own the land, but you can buy a 99-year leasehold, and you can use the land (or sell your leasehold on the open market) as long as you continue to pay the rent. You might also be able to extend your leasehold when it expires, but that is up to the government.
So the expiration part is different, but "taxes" vs "lease rent" is just semantics.
