As an example, Allan Beats, who has run the specialty sci-fi shop Borderlands Books, just closed down his adjoining cafe. He was clear about the problems, and crime doesn't come up: http://borderlands-books.blogspot.com/2019/04/borderlands-ca...
Or Lucca Ravioli, just down Valencia Street, closed on the same day. The owner was selling the building, and there's no way anybody could buy the business without having millions to buy the building too. In sum, it was real estate costs: https://www.sfchronicle.com/food/article/94-year-old-Lucca-R...
I absolutely agree that crime is a problem; I've had 7 bikes stolen over the years. I also agree that the insane rents guarantee people will end up on the streets, and homelessness is comorbid with addictions, which are often fed by crime. But this strikes me as overdramatic. It makes me wonder who funds the organization that produces this.
