It seems easier to imagine trading across Everett branches, assuming one thinks they exist at all. They come from similar starting point but can end up very different. That reduces severity of problem 2.
Yes I think both objections are considerably weaker when the probabilities come from the physics of our actual Universe. While it’s still tricky to pin down the “correct” decision theory in this setting, quetzal_rainbow’s comment here includes a paper that might contain the answer.
