You are looking at this wrong. The point here is making it easier to build larger buildings and smaller units. Density and more building will increase land values, yes. We shouldn't strive for land values going down. But build enough, and floor value go down. This is the efficiency of land use increasing ahead of of demand, decreasing prices. Public housing is needed because it is quite the private sector cannot be relied upon building enough to decrease precises. Even without all he zoning bullshit, housing is still quite an inelastic marke.
