An ethical question

David Friedman asks the following question:
“Assuming that airline passengers will soon be allowed to use their cellphones mid-flight, is it ethical not to wrench a phone from a loud talker’s hand and twist the earpiece off the phone, thus rendering our offensive communicator phoneless?”
It will be interesting to observe what etiquette and/or rules emerge voluntarily. Maybe we will soon see “talking” and “nontalking” sections on airplanes. Of course, if a cong gets personally offended (as is likely) airlines may be coerced into enforcing the cong’s rules.
