The larger point was that incentives flip as soon as you become a homeowner. As a renter, you are hoping for housing prices to go down and would like to see this happen via increased housing supply, deregulation, or even a local economic downturn as someone suggested above. But as soon as you become a homeowner, you want housing prices to level or increase because a large portion of your net worth is tied to it. So you suddenly want new housing supply to shrink, increased developmental regulations, and a booming economy in your area.
