"I'm not talking about orthodox utility theory ("EUT"), and I'm not trying to say that it's currently a good theory, either." The reply button is missing below so I'll reply here. The issue is that the major results of economics in this sort of area are been effectively destroyed by EE. Prospect theory for example is completely gone. There may be places where people's behaviour isn't rational but research into that needs to be effectively carried out again from scratch. The main "evo psych" results in economists have been effectively disproven. So you might be right that people don't act rationally but all existing research into that area is currently dead in the water. It's start from square 1 again.
