Re: I get I'm in a microscopically small minority, but...
There are many for whom working from home doesn't work well, even if their "job" doesn't require them to be in the office:
* People in shared, rented accommodation, who have little private space
* People in cramped accommodation with young children around
* People at the start of their career, who need to work physically close with others to learn
* People for whom the office is the only social contact they get (akin to some lonely elderly people who pop to the shops daily just in order to talk to someone)
It's fine for people like me who are established in their career, have a stable family life, and a house large enough for me to have a separate office where I can close the door. And long may it continue for me. Many don't have such luxury.
