Tangential: Here in India we have security guards with hand-held metal detectors in malls, railway stations, and urban transit rails (metro) stations.

The first time I visited a different country I was surprised to see my friend accompany me to the check-in counter and even further to drop me off. In India they wouldn't let you enter the airport if your flight doesn't depart soon enough.

I don't think anyone in the US really cares about metal detectors, humans don't naturally contain metal and it is done completely hands off with no extra visual or biometric information or saved data. Plenty of people in this thread who opted out of other security measures still walked through a metal detector without any special note. Court houses and police stations have often have metal detectors that even a Senator or President would have to walk through. The same cannot be said of direct imaging of your body though or facial recognition or anything. If you wouldn't put your children through the process to go into school each day then it seems completely bonkers to require it for any form of mass transit.

It used to be normal in the U.S. to walk people to the gate until 9/11.

Now you can escort someone to the check-in counter and up to the security checkpoint, and meet people at the luggage area to help with bags.

But in practice it seems rare to do so if there isn’t a particular reason, probably because you’d have to pay to park or ride transit and it’s usually a trek beyond that. Honestly if they allowed you to go through security with the passenger and wait at the gate, I’m not sure how many people would even do it here (or how many passengers would want their loved ones to do so).

Pre 9/11 you could go through (useless) security without a ticket but longer ago there wasn't even security. And in some places the "gate" was...a gate. In a fence. So being at the gate meant walking from the street up to the fence. Good times.

You can walk someone to the gate, you just have to have a ticket.

not letting outside people at the luggage area seems fine to me, if anyone could enter there the number of stolen baggage would skyrocket.
