Your only response to someone finding this a gross overreach is to try and strawman them by suggesting I'm personally on the list?
I'm not defending billionaires any more than I'm defending an average person. Going down the road suggested (putting yearly or lifetime caps on how much CO2 you can produce) is frankly terrifying.
Tax the hell out of the fuel, charge larger landing fees, etc etc are all better options than having some sort of invisible countdown over everyone's head that for CO2 emissions.
