Society has become increasingly alienating and lonely, going into an office is just a way of papering over that.
Companies haven’t built strong cultures around communicating and mentorship, going into an office is just a way of masking that.
Personally I have worked with and felt camaraderie on distributed teams with people I’ve never met in person. I know it’s possible, but it requires doing things differently than business as usual.
When I started working from home, the situation flipped. Suddenly I was the one often organising these social trips, because my social energy was no longer being used (as much anyway, I was still talking to people regularly, possibly even more so). Working in the office was convenient, I could fill my social needs without even doing anything, but it wasn't real. I wasn't actually socialising with people or seeing friends, I was just sitting near people for 8 hours and that tricked my brain into filling that bar.
Personally, I decided I'd rather than inconvenient truth than a convenient lie. Though real socialisation is a lot more difficult, it's also a lot more fulfilling.
Not saying this is the case for everyone certainly, but that's how it's been for me.
