But I'm annoyed with this psychology that, if it were born into a world where spells and potions did work, would pine away for a world where household goods were abundantly produced by assembly lines.

Why do you desire to have cross-world consistency? You are only going to have to live in one of them. No Dutch book can be made against us by selling us tickets to that world here and then selling us tickets back to this one from there. If such transport were possible, than I agree that we need to reexamine our psychology to avoid constantly being on the bus between worlds. Until then, what's wrong with having world-dependent preferences?
