The author of this article as well as many comments here are talking about this as a "third place" issue, but "third place" is 3rd because there's 2 others before it: home and workplace. From what I can tell, the author is really looking for a workplace.

I think the problem is that some WFH-types[1] have co-opted all the third places and have turned them into cheap workplaces, and coffee shops can't afford to be a coworking space (1 coffee for 7 hours as you say, which I'm sure more people do than some people here believe).

[1] I say this as a 100% remote person myself. But I've never felt right going to a coffee shop or restaurant and sitting there for more than an hour or so.
