Correct. There is a religious libertarian belief that somehow changing zoning laws will "fix" the problem. No numbers are ever given (maybe prices would stay level for a few years) And no one notices that the extremely dense housing of Manhattan did not make Manhattan cheap.

If they want to fix the problem they'd need large tracts of very high grade housing rented non-profit, (never sold) on government land. The competition from this would drive prices through the floor.
