I generally agree that the lack of taller buildings is mostly regulatory, at least in areas not prone to earthquakes. Look at the bizarre weirdness of air right laws, and especially the buying and selling of air rights, which has caused a rise in odd needle-thing super-tall luxury apartment buildings in cities like NYC.
