After people flooded the city and drove up rents during the dot com boom and then fled the city when the bubble burst, real San Franciscans were still there. And if it happens again, they'll still be there afterward. And in 50 or 100 years, they and their families will still be there. How many coders working at startups in the city today can say the same? Who do you think should have more say in the future of the city? Those who care deeply about it's past, present and future - or those who are only looking out for their own short and medium term housing needs?
The old guard - who have the power - wont allow your suggestion to happen in our lifetime. The best you can hope for is slow, methodical babysteps in that direction.
As an aside, San Francisco is denser on paper than in real life because of how its borders are drawn relative to other cities. The core of Chicago fits the population of San Francisco into 31 square miles with an average density of 25,690 per square mile. 1.3 million people in Chicago live in a neighborhood with at least the average density of San Francisco, with a total average density of 22,240 per square mile. If you take a subset of Chicago neighborhoods with the same average density as San Francisco, it has about 2.4 million people.
