You're forgetting the most important one. Having a bunch of your money tied up in an illiquid asset that is subject to all manner of government micromanagement gives you a huge incentive to see to it that the government doesn't get progressively more shitty toward you than it already is.

Yep, saying it's an age thing is missing that every homeowner is directly financially incentivized to ensure prices go up. I literally get physical printed mail (against my will) every other week telling me about the health of my neighborhood where higher home sale prices means better. Being older makes a person more likely to be homeowner, they got the causation backwards.
