I somewhat agree, but on the other hand its not the right place to do it.
If somebody would come and play bagpipes, or start yodel in a courtroom or parlament they would be asked to stop too. And i bet if in those cases they would not stop, they would get reprimands too. No matter how cultural it is.
To be honest the planet does not care how you compute it.
Quick google-fu said private jets are about 1,8% of the total airtravel pollution. If you want whats good for the earth, focus on the half empty and empty commercial flights that big airlines do because they want to keep their hangar places. That makes much bigger part of the overall pollution.
I say: let the rich fly, just make it so they pay enough taxes for it compencate for it.
