Am I missing something? I think this answer is very simple: rationality and winning are never at odds.

(The only exception is when a rational being has incomplete information. If information tells him that the blue box has $100 and the red box has $0, and it is the other way around, it is rational for him to pick the blue box even though he doesn't win.)

Even rational beings usually don't have complete information.

Yes, I agree. I think being rational is always being aware that everything you "know" is a house of cards based on your assumptions. A change in assumptions will require rebuilding the house, and a false room means you need to challenge an assumption.

I'm just arguing that a false room never means that rationality (deduction) itself was wrong (i.e., not winning).

All a rational being can do is base decisions on the information they have. A question: is a rational position based upon incomplete information that leads to not winning really an example of "rationality" not winning? I think that in this discussion we are talking about the relationship between rationality and winning in the context of "enough" information.
