I'll give it a shot. Every city has rules about what you can and can't build within its boundaries. Even lightly-regulated cities like Houston still have rules about density, lot sizes, and what you can build where. There isn't such a thing as a city without "government intervention." The current rules were put into place by previously powerful people who wanted the Bay Area to be low density. There are new powerful people who want to change the rules so it can be higher density. Other people (not the people who are the main focus on this article) also want the local government to help pay to build homes for poorer residents. There are families which have been living in these areas for a long time who can no longer afford to stay. Many communities are only strong because there are people who have been there for a long time, who know each other and have worked hard to build that community. Kicking them out to make room for new comers, who may only be there temporarily, in time weakens the quality of life for everyone.
