I'm a frequent traveler and see the TSA has 90% theatre.
Do you care to identify the 10% that you consider non-theater? Because I travel often, and I don't see it. There is, for example, not even a consistency with respect to how they do pat-down when you refuse the scanners. It really seems like they are making it up as they go along (or maybe it is city-based, I haven't compiled data). The only consistent thing they are taught to do is to check behind the ankle.
