Why would landlords hate such a system. They can trivially pass on any tax to renters and have the incentives to figure out the loopholes in the tax code. It’s already common for single unit corporations to own rental properties.
Instead of taxing based on who owns the land, tax how it’s used. That way more units will be built increasing supply.
But then you’ll run into the real problem, not landlords, regular home owners who largely have a revealed preference to live on giant plots of land, in big houses far from multi unit dwellings. They’ll continue to use restrictive zoning to limit supply and keep prices up.
Because that means apartment buildings become illegal?
Homeownership is all well and good, but sometimes you really do just need a place to live for a year or two, and having to do a full-fledged real estate transaction at each end of that period is a lot of friction.
The tax the poster proposed was a de facto ban which was my point. But even then it wouldn’t work because some land is more desirable than others and by encumbering land ownership you encourage those that own the more desirable land to extract as much value as possible.
The thing we are dancing around in this thread is do landlords largely determine the housing prices. I think not. I think it’s supply constraints and government subsidized mortgages. These are largely issues driven by regular home owners not landlords.
I like a system whereby individuals can own between one and a bit and three somewhere (including provision for commercial property where large facilities need to rent many people's fungible extra-property rights in some way). Mentioning 100% tax is just to head off idiotic straw men about passing the tax on to renters.
Also allowing benefiting from or even rent seeking on only the increased value of very recent property improvements (like taxing at the value it held 5 years ago with some buy-or-sell challenge type provision to prevent undervaluing).
