> It’s different when there’s a compelling physical need here. If the person in front of me has a hurt back and can’t bear sitting upright, and I knew about it, I’d put up with it as best I can in the interest of we’ve all got to get along. But in the scheme of things, not that many people are unable to sit up and not crush their neighbors.

How would you know whether or not the person in front of you has a compelling physical need? Are they supposed to explain their health concerns to you in the hope that you deem it sufficiently acceptable for them to do what they can to be comfortable? It’s unreasonable to expect someone in physical pain to suffer the indignity of explaining themselves to someone they don’t know.
