You and I would probably agree right off the bat on reducing the ability for neighborhoods to reduce housing construction.
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.
