If TSA dismantled the whole apparatus of airport security erected after 9/11, I suppose it would make everyone here happy. But I wonder what kind of economic impact it would have on the airlines. Right now, security theater is keeping the airlines afloat by persuading people not so enamored of flying that it is safe to fly. But would enough of those with a weak attachment to aviation simply bail out to put all the airlines in bankruptcy? I think we could really contemplate dismantling TSA if there is no economic impact. After all, the people who complain most about TSA are already convinced they are on the safest travel mode. No person like that is going to stop flying just because a plane here or there explodes.
