A few comments:
1) we already have property taxes so I don't understand the objection; a land value tax is just a property tax with a different way of assessing value.
2) I don't think this idea of "not owning property, only renting it" is actually that crazy if you take a long term view over it. Land is a finite, shared resource. We already acknowledge that you don't have absolute rights over land that you own in the same way you do over, say, a toaster. We place all kinds of restrictions on what you can do with it, we tax its ownership, we have eminent domain laws, etc.
The idea of treating land as a pure asset has had a lot of negative social effects and ultimately will lead to a kind of neo-feudalism where the megarich own everything and the underclasses are perpetual renters.
