If the wealthy and powerful continue buying land at the rate they are, through private equity firms for example, then we could end up in the neofeudalist scenario where us peasants can't acquire the capital to buy the land back (like in England before the Black Death around 1350 broke the nobles who could no longer afford essential workers). Then the only options left to us are taxes/regulation or revolution. Since the capitalists would have captured government by that point, the only option left may be revolution.

I could also see scenarios where we go full vanlife, although more vagrancy laws are being passed, and flock cameras could be used to enforce high registration fees to the point where it's no cheaper to live in one's car than to rent.

Admittedly those scenarios are pretty out there. Probably what will happen is something outside of what we expect. For example, the "rabble" may end up being the blue collar workers that we used to think of as the conservatives. They don't take any crap, so would probably requisition land to feed their families and guard it with firearms. If the authorities tried to take it back, armed conflict could very quickly squander any remaining goodwill held towards the capitalists.

We could play all this out with game theory, but I suspect that most scenarios end in revolution. That's probably why billionaires don't talk about the bunkers they're building. If they truly don't see a way out of the end times, then I don't know why they persist in doing what they're doing. At some point it would simply be in their financial best interest to raise their own taxes, or face the wrath of the people they formerly employed.
