But as others have pointed out, a lot of the TSA processes (taking off shoes, laptops, liquids, etc.) are pointless.
What prevents another 9/11 are the cockpit doors, which have nothing to do with TSA.
Before 9/11, airplane hijackers were like bank robbers: idiots trying to get some cash. If you just followed their orders, everyone would mostly get out alive.
Even mid-9/11, when it became clear that the hijackers were using the planes to attack civilians (at the necessary cost of the lives of the passengers), people stopped cooperating and stopped the final plane from reaching its target.
Even if someone walked into the cockpit with a gun they'd get nothing for their trouble but an immediate nosedive as the pilot sacrificed the plane to protect whatever the intended target was.
Nowadays, any would-be hijacker is going to get immediately dogpiled and beat within an inch of their lives before they ever reach first class.

I do know flying from Los Cabos Mexico where TSA doesn’t matter, I didn’t have to remove my laptop a couple of years ago
I'm not saying that we should let people board in full armor again, but surely there is a happy medium?
People do it all of the time for other reasons.
Too lazy to read the many GAO reports that all demonstrate TSA accuracy at finding dangerous items never topping 5%?
