Let's define an action as instrumentally rational if it brings you closer to your goal.

Suppose my goal is to get rich. Suppose, on a whim, I walk into a casino and put a large amount of money on number 12 in a single game of roulette. Suppose number 12 comes up. Was that rational?

Same objection applies to your definition of epistemicaly rational actions.
