@gannett I'm not being argumentative, I promise, but I don't understand how you can genuinely not understand the value of in-person interaction?
Presumably most of the people here claiming that working in complete isolation is absolutely fine wouldn't want to conduct their marriages, relationships with their children and/or friends via Teams meetings only?
In which case you understand the value of human interaction versus that which takes place on a screen. The previous poster who said that life was moving increasingly online isn't wrong, but if human interaction has any value, then it has value at work in a different but related way to the way in which it has value for family and friends.
You simply cannot build the same relationships, trust, contacts, network via screens and emails as you can through in-person meetings. I won't give details from my own profession, as it will out me, but I'm sure the same principle is true in most professions.
As so often happens on Mumsnet, this conversation has become really polarised in a way that it shouldn't. Flexibility, hybrid working, moving with the times, some WFH time... all of these things are important. But so is in-person interaction and so (for most people, leaving aside extreme disabilities) is leaving your house occasionally to do some work.
And also... as a previous poster said... the idea that evil capitalist landlords are the only people who pay the economic price if city centres collapse - that's very naive.
