And also allow more flexible commercial real estate to be built. For example, in 1985 San Francisco passed Prop M which caps the limit of area of office space to ~1e6 square feet (think roughly 1,000 2-BR or 4,000 desk spaces) apartments that can be built -- disregarding any population changes or even if space is torn down. Meaning if the entire city was razed (say due to an earthquake) that amount per year. Iatrogenics abound
