It's much more than people scared of number on paper going down. There's an entire industry around mortgages, refi, securities, reverse mortgages, credit lines, credit swaps etc basically property is a giant credit card to get more liquid cash. So the economy will get nuked if things start to unwind too much. It's a big problem and id like to see a bitcoin standard, get things on a sustainable humble path. That's never going to happen until things implode and get so bad people say okay maybe we bought a few too many 5th wheels and corvettes.
