If your net worth is tied up in your home (house rich, cash poor), you can't put that money into savings or investments. My house is "worth" 2X what I paid for it 11 years ago, awesome. It's not helping to pay the increase in taxes, homeowners insurance, groceries, that have gone up, up & up.

That's fair, excluding primary residence makes sense just like retirement accounts.
