I think you can make the flip-side argument that private property in land is the least obviously defensible kind of property for people to really own (in an absolute sense), because nobody produced it and there is an inherently fixed amount of it (except for unusual cases like land reclamation).
I remember feeling sympathetic to the argument that property tax means that you don't really own land but just rent it from a state, but if there's a particular kind of thing that you possibly shouldn't really be able to own but should just rent from some institution purportedly representing a community, it now seems like it's more plausible that that should be land, as opposed to movable property, labor, debt, and contractual interests.
This is the best argument I've seen for property tax, but coupled with a lack of something like UBI it means you can't live a life apart from society. You must always participate in work to justify your continued existence.
You don't ever really own anything. The natural state is that some bandit with more guns comes and takes it from you, and if you want to possess something you better be the bigger bandit.
Feudalism and the modern tax-supported state are two approaches to avoiding constant conflict. With feudalism, the king protects your holdings, and in return you owe him military service to support this protection. With a modern nation-state, the state holds a monopoly on physical violence, and you pay taxes to the state so they can maintain a standing army and legal system to enforce your property rights.
Debates over which form of taxation is best are better framed in economic terms rather than moral terms. Which forms of taxation encourage beneficial pro-social behavior and discourage anti-social behavior? There's a good argument that wealth taxes (particularly when taxing natural resources like land, data, the electromagnetic spectrum, CO2 emissions, or pollution) are much more effective at this than income taxes.
It's basically feudalism. I'm not against taxes in general, but property tax means you never really own anything.
