Herding people into open office spaces has already been proven to hurt productivity.
Also in respect to Bay Area it certainly hurts productivity if you have to spend 2 hours everyday in commute. Unless your role means constantly blabbering on the phone you just can’t work while commuting. And I would argue if you do spend most of the time yapping on the phone then it shouldn’t matter if you are doing it remotely except for few cases where face to face is absolutely necessary.
From Harvard study in 2018 comparing pre/post open-office.
