I think that Omega being a perfect predictor through some completely unspecified mechanism is one of the most confusing parts of this problem.
It may be a truly magical power, but any other method of stipulating better-than-random prediction has a hole in it that lets people ignore the actual decision in favor of finding a method to outsmart said prediction method. Parfit’s Hitchhiker, as usually formalised on LessWrong, involves a more believable good-enough lie-detector—but prediction is much harder than lie-detection, we don’t have solid methods of prediction that aren’t gameable, and so forth, until it’s easier to just postulate Omega to get people to engage with the decision instead of the formulation.
Now if the method of prediction were totally irrelevant, I think I would agree with you. On the other hand, method of prediction can be the difference between your choice directly putting the money in the box in Newcomb’s problem and a smoking lesion problem. If the method of prediction is relevant, than requiring an unrealistic perfect predictor is going to leave you with something pretty unintuitive. I guess that a perfect simulation or a perfect lie detector would be reasonable though. On the other hand outsmarting the prediction method may not be an option. Maybe they give you a psychology test, and only afterwords offer you a Newcomb problem. In any case I feel like confusing bits of problem statement are perhaps just being moved around.
