I think being allowed to work from home doesn't mean that people actually will all suddenly start doing that. My boss put out a survey a week or two ago among my org (30 or so people), and 70% said that they want to work from the office, full time, 20% said some time or most of the time, and 10% said fully remote. And this is a group of people that would be largely well suited to working from home (young, no kids, etc). I just don't think that this will change much.
