Let's start by all agreeing that the proposal to tax land at 100% (of what?) is a bit nutty and not going to happen. Possibly this is satire. Poe's Law. But toned down, would an increased, progressive tax on land ownership have positive benefits? More tax income, yes. And the author isn't wrong in that such a change would serve to level land values (and therefore rents, probably) out a bit. There would sure be some upheaval bringing it in ("my mom can't afford to live in her family home anymore after 40 years!"). But it's an interesting proposal.
