I hate hearing people, talking or anything. I moved to LA for work and loathe every second of it. So that is my mind-set to start off.
But.
Your argument appealed to me. Tremendously. I am against the government regulating essentially anything, with the limit falling at 'where the actions of one gravely affect another without choice/alternative".
Here though, is my thought, and maybe I'm just defending my own peace-of-mind desires. And this might sound like I am being facetious, I am not:
Some people can't take that clammer, and it is all they can do to stay sane in a quiet, peaceful plane. Add on a bunch of noisey people taking about how they scored the big sale, or 'are sooo wasted' and the amount of in-air violence will climb.
I think leave the law. OR an alternate solution, let airlines choose whether passengers can talk. [I'd go on the quiet-people plane]
But airlines are different than the public areas. I am/we are a captive audience. If someone decides to have a loud, annoying conversation; I can't do anything. The point I'm trying to make, the one that to me validates a regulation here, is that I can't choose to not listen to their phone call; which is unnecessary.
