... with a vote. And subject to the takings clause.

The government can also just take your deed and property, again subject to the takings clause, so long as they pay you back. Or claim someone was slinging crack there or something and not pay you back.

If you're including things subject to the democratic process all the above is on the table.

Also plenty of things written into the deed don't mean shit. It's quite common to read a deed that says something like, in more fluffed terms "no black people allowed." This got baked into lots of deeds back in the day and never got changed because removing covenants to a deed is usually next to impossible. It doesn't mean dick because again the government can simply add or subtract by fiat what your deed actually means.

What your deed is and isn't is a lot closer to how zoning works than you think. Ranchers found this out when their transferrable private property grazing rights tracing back to the very founding era of the USA got usurped by the government and ultimately the BLM who turned around and actually said they're public federal property (which resulted in things like, the Bundy standoff).
