Have you looked at age-of-consent rules across the various states? Boating license age requirements? How have those two completely unrelated things have-or-not changed over the past 100 years across all 50 states? Age for kids to sit in the front seat of a car? Learn to drive a car? Get a work permit?

States have age-related laws at an insane level. I don't know what you're on about.
