What I was asking for was an existence proof (i.e., an example) for a claim being made about how the theory plays out in the real world. For such a claim, I most certainly am entitled to that particular proof.

I repeat the assertion from the grandparent. You made this demand multiple times in support of a point that you explicitly declared was about the behaviour of theoretical rational agents in the abstract. Please see the quotes provided in the grandparent. You are not entitled to real-world existence proofs.

If you wish to weaken your claim such that it only applies to humans in the real world then your demand becomes coherent. As it stands it is a non sequitur and logically rude.
