Sure he was a mass murdering psychopath so it was all being done to try and placate him, but it's still far more likely a situation when the concept of owning the most powerful being on the planet comes up.
he'd be a refugee with no planet to return to, thus stateless, and granted citizenship by the country that accepted him

IIRC, there’s a Superman comic that states that nearly every country on Earth has given him citizenship.
