Having said that, there is a lot that places like DC can do to improve things - exploit and encourage the beneficial aspects of density - without scrapping the height limit. I'm always struck at how big chunks of DC look quite a lot like LA. It isn't the height limit, it's the fact that so much development in pretty dense areas privileges and is centered around automobile travel. You get parking lots where there shouldn't be parking lots, making areas less walkable and appealing.
