The article to me is about the cost of a box to sleep in SF. The person they interviewed was just one of the renters. There are all sorts of people living in that place. Most I would wager are the people who cannot afford anything better.
Why do you think minimum wage workers should not be allowed to live in SF? If everyone is writing code, who would make the food? Who would deliver the packages? Who would clean the workspace in your office? They don't deserve a place to live near you even though they are providing you with all kind of services? Genuinely asking here because I can't fathom what you were saying when you said SF is not for minimum wage workers.
