Well the reality is that wfh is a trend and it helps with the issue that I'm talking about. It's not hypothetical, it's happening now.

Does it, though? Socializing at home during work hours is not the same thing as socializing outside of work hours.

Plus, people still work 8+ hours a day, so you can't really interact much with friends.

The main thing you win is geographically, I guess. No more time lost in commute plus maybe less time lost meeting with friends because you don't have to go from the office to the meeting place (though that will obviously depend on how far your friends are from your home).

You're not really socializing with people in the office either, you're working with them. Without a boss around looking over your shoulder, you have a lot more time to socialize if you want. Go get a coffee with a friend, your partner, your kid...

I'd also describe the office as anti-social as I would not voluntarily spend my time with the majority of my co-workers and having to be around them day in and day out is extremely draining and demoralizing. I find surrounding myself with people I actually care about and have real bonds with to be far more positive.
