I think the biggest issue is that people are lonely due to the pandemic, and are conflating that with working from home. You can have a strong social life and working from home. For others, unfortunately the only socialization they can get is forced interaction with coworkers at the office.
I can see what you're getting at, and I thought it was the issue for me, but I've come to realize that it's not a loneliness/lack of socialization thing. It's just that I really treasure in-person interactions with the people I am working on something with. I got into software engineering because I like solving problems, but also because I love solving problems with really smart people. Turns out that it feels really…
So long as the other person feels the same way. One of the reasons I enjoy working from home is people can no longer wonder by and shatter my concentration because they're on a break. They can ping me in chat and I'll get to it in my break.
