I don't think it's straightforward at all. The premise of the article gives a lot of counterarguments. The developers are bypassing these laws to build luxury apartments for the rich, and so even if height limits are the only reason buildings are twice as tall (which is probably not true), and there was twice as much housing, it could very easily be housing that's built for the mega-rich (think a high-wealth overseas person who will purchase it and then rent to a high-income local professional worker). That living space would be anything but "affordable". Not all housing is created equal.
