There was a time in this country when parents used to tell their children that one of the things that made the Soviet Union so horrible was that you had to show your 'papers' to travel anywhere.
If I pay for something, I should not have to show ID.
If the airlines want me to produce ID, they should make it worth my while by offering a discount or allowing me to board without having my luggage searched without a warrant.
Until then, I'll simply drive.
