Price controls tend to backfire spectacularly. Rent control like Germany does it would probably be okay, but that's a much more moderate form than is typical in America (for places that do have rent control).

There is one fairly straightforward solution for housing, at least: lots of public housing. Ideally, modeled on successful public housing policies from places like Singapore or Vienna.

Getting lots of public housing would probably involve a lot of things that YIMBY's push for private housing too; you'd still want upzoning, you'd still want to get rid of processes that let neighbors stop developments for anything they want (eg. "it's not okay that this tall building will cast shadows"), you'd still need to get planning commission to process permits on the order of days or weeks rather than months and years, etc.
