I came to say exactly this. In addition, we can't forget the people who have to work in the city but can't afford to live there, so their lives are made vastly more difficult.

Sometimes the commute is just too stressful, even if you live in the city. My partner's well-being has visibly improved due to going into the office only when necessary.

Maybe WFH should be renamed to something else. It doesn't capture all the subtleties of flexibility and choice we're asking for.
