Indeed, homes are some of the most liquid form of wealth, easily leveraged with loans to buy even more property. And home values are one thing that governments are most likely to protect through drastic policy changes. Sure, you can take out a loan backed by your diamonds, but it won't be on terms as good as that of your home.
Home wealth really is one of the strongest forms of wealth there is, and people trying to pretend it is not have no concept of how lucky they are, or even what wealth really means.
People without this wealth are forced to pay their rent to others, who accept both the rent and then the real estate gains.
