The whole thing is a bit of a hypothetical thought experiment anyways. The licensing in those locales is different & the list of acceptable content is different in them as well. Netflix cannot simply give a child access to that content because their parents happen to be in another country. It's a violation of their licensing agreement and also can land them in jail in some circumstances.
