> A large portion, maybe even the majority, of travelers simply won't feel safe without it. I've had and overheard multiple conversations at the airport where somebody felt uncomfortable boarding a plane because they saw the screening agent asleep at the desk.

I’d hazard that this may be true now, but this feeling was created by the same “security measures” we’re discussing.

Anyway, such major population-wide measures shouldn’t be about stopping people being “uncomfortable” - they should be about minimising risk, or not at all. If you start imposing laws or other practices every time a group of people feel “uncomfortable”, the world will quickly grind to a halt.
