I agree with everything you said. I also support the YIMBY solution (building more housing to drive down prices). However, my only point (which HN seems to downvote) is that the YIMBY party in San Francisco has an image / branding issue. They are perceived as being techies out of touch with lower income and minority groups. As you have rightly pointed out this is probably a flawed view, but it is a branding issue.
