>When someone tells me to arrive 3 hours before my scheduled departure time, to me it's disrespectful that they would waste so much of my time so unapologetically.
Technically most airlines only require you to arrive 60-75 minutes before departure for check-in. The 3 hour advice is just advice that you're free to ignore, but is probably a bad idea to do so given how much money/time is on the line. The 60-75 minutes might still sound like a lot, but gates typically close 20 minutes prior to departure, and boarding starts 40-60 minutes prior to departure, so they're only really asking you "waste" 20-30 minutes.
>There's no other situation in my life where people can control what I wear, or presume to separate me from my keys and wallet.
courts/some government buildings do similar security checks, and in some countries they do such checks in even more public places (eg. subways/malls/cultural sites).
