What would you advocate to lower the cost of housing by 50%?
Personally I suspect the land cost is one huge part of why people don't build their own homes today. Today's version of the sears catalog home would be like "2 dozen people buy a small plot of land together in/near the city and build a condominium to share the land in a cost-effective way". But while random people can build a basic pre-fab home with lots of determination, they probably can't build a 5-over-1.
