Everyone working in an office (maintenance excepcted) could work from home right now. The fact so few of us do, and that so many companies (read "people who are invested in urban office space") force employees to work from offices.
I too love to meet my colleagues in person, but the cost for society, and for myself, are non-trivial. I would love if we had a weekly office day, so we could have meetings, lunch, discuss work, projects, intersections on what we are doing, and so on.
