How do you see that happening, exactly? People are used to the idea that land prices should skyrocket indefinitely and everyone with a mortgage engages total chimp mode if anyone tries tapping the brake on that bubble. All the red tape and restrictions in new development are intended to artificially boost housing prices, and if somebody in office even slightly challenged that they'd turn the entire middle class into single-issue voters wanting to drag them into the street, and the property development lobby would fund as many primary challenges as it takes to put them there.
Oh nevermind, you're just so retarded you think you're the first one to figure out simple solutions to all of the world's problems.
