Depressing home purchases might well be a good idea. Right now people treat them as investments rather than mere housing, and as a result that market is thrown entirely out of whack.
Indeed, home prices increasing at more than a modest rate is a bad thing for everyone in the long term.
Homes should be investments in the same way that a factory or warehouse is an investment. You buy instead of renting in order to fix the cost of doing business over time, not to speculate on potential future values.
Yes, with "Land Bank" being a big thing now, with people just buying up land and holding it to simply fight inflation, things are just going to spiral out of control one way or another.
