>Density is the response to land scarcity that takes away power from landlords, not the other way around. "Density" in my comment is population density, not construction density. Unfortunately, construction density (and height) is restricted by zoning and all kinds of bylaws. Most residential areas in North America allow only single-family houses and prohibit multi-tenant buildings with 3-4 floors or more. Landlords benefit from such zoning rules immensely, because they drive land price up.
