It wont happen, but I'd love to see a more hands off approach. It would be cool to have things divided into standard lots and auction them off at a standard rate. Have a couple basic rules around minimum density, prohibit re-selling, and probably have a maximum number of lots that can be combined. You would probably need huge towers in certain locations, so that would be left to the bigger developers. It would be an interesting way to spread some of the wealth to smaller developers. Probably make for really interesting urbanism too.
