Even Paris, a city that has banned high-rises, has a population density about 2.5x that of San Francisco. I realize SF doesn't want Miami-style condo towers everywhere, but there's a lot of room to densify just by putting in more mid-rise buildings in the 5-6 story range, rather than having so much of the city be low-rise.
