Doesn't fix it. People end up buying bigger homes just as a place to park money. The root of the problem is that housing is a subsidized investment; you're getting free money from the government by taking out a mortgage, and the market will figure out ways to take advantage of that with silly results.

Why does this matter? The problem stated is lack of supply generally, not that people want bigger homes, right? Who cares if people are parking their money in a bigger home if they only have a single home?

The lack of supply is because of a lack of desirable land. I don't think viewing it through the lens of "houses" getting more expensive is correct, as many old homes being purchased for 500k+ near me will be immediately torn down. There's a finite supply of land in driving distance of a city and bigger suburban houses mean less homes can be built. If you don't view it like that, bigger homes still require more materials and man-hours.

Bigger homes take more space, and that's the constrained resource in places where houses are expensive.
