I think there's a distinction between fully remote and using an "office" as a collaboration space where people come in once every week or two to get to know colleagues socially and talk about work-related things. I'm not sure I'd enjoy being fully remote but I also don't like five days a week office working.

Plus, if you're only going there occasionally and never for the entire working day, it's not really a "commute" any more. I would never accept a 90 minute commute but if I was doing it on the train once a week and not at peak hours that would be totally fine.
