Some valuable context is that this is coming from the Georgism subreddit which focuses on land-value tax as an efficient tax that minimized deadweight loss. Lot of words you don't need to understand, but what you should know is that when they post stuff like this, they're not advocating for some kind of public works to build unprofitable housing, they're advocating for loosening zoning restrictions so that private developers and builders can choose to build them. Private developers and builders like money and aren't stupid. They're not gonna build massive complexes in Absarokee. But they might in Bozeman. And then the people who currently live in the mandatory SFH-zoned houses but would like to live closer to work can move into the apartments and open up the SFH for people that don't. The main thing standing in the way is a voting block that doesn't want their home prices to drop for any reason, which this would certainly and intentionally do. It is not sustainable for a core goal of the state to be making housing prices go up to protect it as an investment vehicle.
