Q: My and my parents are in different countries. I want to add my mom to Family Sharing but... I can't. It says that we need to be in the same country.

To setup Family Sharing, both accounts must be set to the same country.

That I already know (it's part of my question). I'm asking: Why?

 

Please, don't answer: Because Apple want it to be in same country.

Nobody here would know. My best guess is different countries have different laws regarding online purchases, privacy, etc. There likely isn't a simple solution to resolve all the laws of different countries into a nice, neat package.
