I know I for one will be going back to the office as soon as possible. However, that's more due to the fact that working from home does not fit with the way I want to live, rather than any actual logistical hurdle.
At the same time though, I highly doubt many companies in the future will go 100% WFH, so all these discussions seem rather academic to me. I feel like the people that want to work from home will get more opportunity to do so, and the people that don't, won't have to. Easy.
When I was younger I think I was depressed. It got to the stage where people would talk to me and I wouldn't talk back, I'd just stare; I'd lie in bed doing nothing; I let my hair grow long because I didn't want to go outside or talk to a barber.
I'm much better now, and I think exercise was one of the key things that improved my general mood. It was a constant sturggle though for a while.
YMMV, of course, and I was never diagnosed or anything.
If they're doing work for their own enjoyment, why should they complain?
