It's reasonable to ask for that and it would probably be up to a local government agency to enforce such a rule.

(In fact Meta's Quest was not available in my country for a few years until Meta changed their mind and removed the need to have a Facebook account as well).

To make Sony care about small countries it would be best for them to band together and act as a group on that. It must hurt them economically

If Sony doesn't have any presence in those countries, as evidenced by the fact that you can't create PSN accounts for those countries, do those countries even have jurisdiction over Sony? More practically, what leverage do they have to enforce compliance? Meta (Facebook) doesn't have any presence in China, so they can safely ignore any takedown requests from them, even if they are actually violating Chinese law.
