I mean, if killing a person or making them fall in love with you are against the rules, it seems that you’re not meant to use wishes to fuck with people. Sure, Jafar does, but he’s the villain - given Genie’s good nature, I’d imagine he wouldn’t let his wishes do that unless the wisher specifically forced it, which Aladdin wouldn’t do.
Fucking with people by making them suddenly be a citizen of a completely new country, or suddenly not be the ruler of the country they previously ruled would probably be something Genie would avoid, and Aladdin wouldn’t press him on it, even if it’s not specifically covered under the quick list of rules Genie gave.
That’s a fair point. I was thinking it was kinda like being the technical prince of the Ottoman empire or some other country that no longer exists - a neat factoid to talk about, but otherwise not really relevant.
