In the abstract, the case for supranational organizations is almost too obvious to be worth making: just as it often benefits individual people to form groups and agree to restrict their behaviour in certain ways, so it can benefit nations to join groups and agree to restrict their behaviour in certain ways. But nations aren't anything more than collections of people. Nations, like societies and governments, cannot do anything. Rather, the people within are the ones taking action. Supernational organizations that constrain member states without the consent of the citizens of those states are just another form of tyranny. You don't need giant bureaucracies to have free trade or free movement of people (or prosperity, for that matter).
