There are certainly hypothetical scenarios in which acausal trade is rationally justified: cases in which the rational actors can know whether or not the other actors perform or don’t perform some acausally-determined actions depending upon the outcomes of their decision theories, even if they can’t observe it. Any case simple enough to discuss is obviously ridiculously contrived, but the mode of reasoning is not ruled out in principle.
My expectation is that such a mode of reasoning is overwhelmingly ruled out by practical constraints.
I understand the logic but in a deterministic multiverse the expected utility of any action is the same since the amplitude of the universal wave function is fixed at any given time. No action has any effect on the total utility generated by the multiverse.
