Actually, this one is simple. ID isn't a requirement to fly; one needs only submit to an additional secondary and Bob's your uncle.
BTW, conflating the conceptual notions of
identification and
identity will land you in serious fallacy trouble. Identification documents come with expiration dates; one's personal identity doesn't. Valid ID does not entail security.@:-)
