My question is simply: Do we have any reason to believe that the uncertainty introduced by quantum mechanics will preclude the level of precision in which two agents have to model each other in order to engage in acausal trade?
No. There are any number of predictable systems in our quantum universe, and no reason to believe that an agent need be anything other than e.g. a computer program. In any case “noise” is the wrong way to think about QM; quantum behaviour is precisely predictable, it’s just the subjective Born probabilities that apply.
