Not everyone should work from home. A lot of people don't like it. A lot of people need the in face connections. Working from home has lots of downsides that have been covered on here and everywhere many, many hundreds/thousands of times.
But a lot of people don't need to go into an office, at least not every working hour of every day. A lot of positions don't. A lot of people thrive fully working from home, some working part time from home and other times in the office, or a cafe, or whatever.
But how these discussions always go is the no-work-from-home crowd effectively saying that no one should work from home because they personally don't enjoy it.
