The problem is people want to live either where it is nice, or within 30 minutes of work.
This creates a supply and demand issue as supply dwindles the demand doesn't, so prices sky-rocket
Solution: Get rid of roads, no roads no cars no cars no parking lots / garages, and a whole list of other side stuff related to vehicles.
All the extra free space then can be put to building more, but unfortunately people don't want to live near "affordable housing" its a NIMBY (not in my backyard) issue...
Or as another thought, don't have a large physical campus, rather tell everyone to work from home or wherever .... then people will buy where there's no supply issues, since no more daily commute
