I'm struggling to see how someone who got $1MM+ in free equity would be priced out of a home they could previously afford; or how the current system that prices people who grew up here out of the entire area is somehow more fair.
Work your whole life and live in a moderately priced home. Housing prices around you drastically shoot up for reasons outside of your control while you're in your 60s. Not fair to be forced to move at that point I think.
It's a good thing you're not forced to move at that point, then. If your home value goes up, you've got a lot more equity you can borrow against. There are many investment vehicles at that point that are very low risk and will cover the meager 1% property tax (less in CA) you'll be paying.
