Doing genealogy, one of the most interesting ancestors I have actually got mentioned in a discussion in parliament for his real estate shenanigans. His wife had inherited some small but vaguely defined land from her first husband. He then became mayor and land assessor, and drew up ridiculously generous borders (and low tax assessments) for that land. No one thought to stop him. At one point during a sale, some officials had commented that they couldn't find that he had title to this land, but they didn't follow up. By the time they complained about it in parliament, it was two generations and many land transfers ago so they didn't think it was worth it to try to unwind it.
The trouble with this is it's a playbook for huge inequality. If there is very little cost to holding onto land, then as soon as someone accrues some, it never leaves their family tree. For example, do you believe that the Duke of Westminster should be the beneficiary of his aristocratic ancestors? He is literally living off of land accrued hundreds of years ago.
He said he'd give them a cut of the rent.

So his parents earned it, not him.
