> In-person team collaboration requires... well, collaboration.

You're confusing things. Collaboration doesn't require you to be continuously in the same room with people 5 days a week, 8 hours a day, and your personal needs to be in a room with someone else does not justify forcing everyone under payroll to commute to the office.

You already need to schedule meetings to be in the same room with someone, don't you? Why would anyone have to waste their time commuting to the office if you didn't booked a meeting?

You're misunderstanding my use of the term collaboration. I'm not using it as corporate speak for "teamwork". I'm saying that in order for me to go into the office with everyone, everyone needs to go into the office. That's an axiomatic self-proving statement.

As opposed to WFH where one can simply do that without other people also doing it.
