There are plenty of us who became extremely productive and can finally enjoy life rather than constantly play the spectacle in the office or sit in traffic for hours. And don't get me started on the ones who are neurodiverse or have any kind of disability.
Overwork can be corrosive to productivity and quality, but that can happen in-office, as much as at home.
But also, working at home does require self-discipline, and not everyone is able to do that. It's also like being a manager, or a company owner. These require a certain type of personality/skillset, and not everyone has it. There's a good possibility that we need external structure. I know folks who rented a desk in a local incubator, during COVID, because they needed the time away from home.
That's not necessarily a bad thing. Some of the most materially successful people in history, have been right bastards, in life. There's a lot to be said for a healthy work/life balance.
As far as neurodiverse folks; some of them can do very well at home.
