Jan, I agree with your references, especially Friston et al. I think those kinds of understanding, as you say, have not adequately made their way into utility utility-theoretic fields like econ and game theory, so I think the post is valid as a statement about the state of understanding in those utility-oriented fields. (Note that the post is about “a missing concept from the axioms of game theory and bargaining theory” and “a key missing concept from utility theory”, and not “concepts missing from the mind of all of humanity”.)
