(Un)fortunately, I think that the reality is that for many people, the office is their social outlet, they are indeed friends with their coworkers (for now anyway), and they live downtown in a 200 sq. ft. apartment with 2 roommates that is 100' from the office.

For folks in this situation, WFH is probably intolerable.

It's just the case that not everyone is in the same situation, and I think people forget that when they make claims that boil down to "WFH is 100% bad and we should all go to the office." (or the opposite)
