Is it, really? The entire current population of the Bay Area is tiny (7 million people across 101 cities, less than a million in S.F. proper). Compare: Tokyo metro area: 37.8 Million Mexico City metro area: 21.2 Million NYC metro area: 20 Million If demand where truly unlimited, then building up S.F. to Tokyo standards or above over the next few decades should be practical, since that level of demand would provide the funds for the growth. Of course, what is really going to happen is that demand will likely stabilize around or below the 15 million threshold for the entire Bay Area.
