I agree with you aside from the out of place sarcastic human garbage quip. It saddens me how every fast food closure in San Francisco is so celebrated in "progressive" online circles, like the Market St. Burger King recently: https://www.sfgate.com/bayarea/article/Burger-King-1200-Mark...
While I mourn the loss of cheap and quick options in SF, I didn't lose much sleep over that particular restaurant. I had sporadic access to the back-of-house at that BK for various reasons (that I won't explain here) and I'm sure it was only scraping by on health inspections. Rats, poor handling of trash, terrible smell, etc. It was closed once in 2016 for some of the above. You can't have a good third place when it's also a biohazard.
All this to say, however, that I agree with you that formula retail shouldn't be demonized by SF as much as it is.
