However, I have to ask you about height restrictions. There's height restrictions because not everyone wants to live next to a skyscraper, which is well, debatable. I can debate both sides of that.
There's also height restrictions because the bedrock of San Francisco is not uniform across the city. In many areas of the city, I don't think you even can build skyscrapers and expect them to remain stable, as we are seeing with the Millennium Tower and the incomplete dome on the Salesforce Tower.
I could consider reducing height restrictions, certainly, but I don't think you can eliminate them completely.
In cities without rent control, like Seattle, development happens a lot quicker. Over the course of half a decade (2010-2015 IIRC) Seattle added more than twice the number of housing units as SF. Rent control's perverse system of incentives leads cities like SF to shoot themselves in the foot.
