The problem with "increase supply" is that existing property owners rarely want that.
In almost all cities land has run out, so the only way to actually increase supply is to increase density. That means fewer single-family-homes, and more townhomes, multi-family, condos, and apartments.
The "American Dream" is a single-family-home, surrounded by other single-family homes, but even with urban sprawl we simply run into the limits of a commute and prices skyrocket.
Ironically we actually solved this problem: Indefinite Telecommuting. But then decided to take our solution that reduces property prices, reduces air pollution, and improves quality of life and then just threw it away because commercial property owners were losing money.
