> I'm saying on average, everyone's ability to get stuff done is higher if everyone can interrupt everyone.

There's no actual evidence of that being true though. It's very much your personal take on it as you've said. I'm also hesitant to ask that if your work relies so much on being able to interrupt your coworkers at a moments notice is that evidence of other issues. Not having power to make decisions on the direction of your work? Poor documentation? Dare I say lack of confidence and/or ability to do your (not you specifically) own job? Seems to me the whole case against remote/hybrid boils down to certain peoples feelings about how they feel comfortable working. Not any actual statistical proof on the matter.
