It reminds me of all the desert shithole land I looked at that had covenants created by a dead boomer back in the 80s that require something ridiculous like "we will only allow a mansion to be built next to our pigfarm."

In theory it's possible to reverse but in practice it requires something like standing on one foot, holding your breath, and reciting the entire bible.

People desperately need housing and even in bum fuck nowhere where I live they are desperate to build a little homestead just so they can have something, and then you have this insanity with people creating covenants that basically have dead people in their graves reaching out to smite living people.

Isn't this (covenants that basically have dead people in their graves reaching out to smite living people) exactly what the dead hand rule was created to prevent? This was a major part of the "defeudalization" that took place between the 17th-19th centuries in most of western Europe, as before then the nobility would entail their estates so as to keep them whole in the senior male line. It does allow for limited postmortem control, but practically not more than one human lifespan thereafter.

Yep this is my concern. They get the (desirable) land / homes and nobody else ever gets to live there.
