It's disappointing to see your comment downvoted because although I strongly don't want people making calls on the plane, your perspective is interesting and you make a good argument :-)

I would definitely agree I don't want arbitrary restrictions, but when jamming a ton of humans from all walks of life into a narrow metal tube, sealing it, and sailing it through the air, we have to have some common rules of conduct to prevent it turning into an unbearable hell for some of the people. Definitely don't want to see governments pass laws or even ISPs, but the plane owners I see no issue with and in fact think it is an important thing to do.
