Since we can't realistically ask everyone to succumb to background checks we at least have to put in some safety checks along the way. It's by design that it's annoyingly slow to get through airport security. It prevents people from rushing into the airport and rushing onto a plane unnoticed. What may look like incompetence is actually very meticulously structured. I really don't think it's that big of a deal. Besides, as airports are going through remodeling they are getting more and more comfortable to hang out in.
