Passenger X's reasons for taking airline A to his destination might be because the carrier's pilots are armed. Mrs. Y's overriding priority is to ensure her young daughters are not subjected to the mandatory pat downs she chooses airline B, because its security personnel profile passengers.
And young student Z's reasons for taking airline C are that they engage in none of these safety practices but offer an extremely low price!
Surely you're not suggesting that
all regulations should be determined by market forces alone?
