Again, I believe it should be on an airline level. Anything else hides the inane costs for these ineffective and time wasting 'protections.' They must be airline employees, answerable directly to the desk management at each airport, so that when one of these yahoos exceeds civility to play strong arm games, they can be fired on the spot.
I get your point and as conservatives we share the same goals. Ideally we would like that, but how do you get there from here?
Step one - privatization, that gets rid of the TSA and wounds it for a generation, hopefully.
(the persistence of bad ideas is incredible and we live in a world of lost knowledge/wisdom)
Step two - privatize airports.
They should be owned like condos with each gate being owned by bidders just like seats on an exchange or at a condo and without limitation.
The streets, ticketing gates, etc. would be treated as common areas and fees would be charged against each gate ownership.
Governments should own/run as little as possible
