I don't think that's true and history has shown it isn't true. The US couldn't stop alcohol consumption during prohibition even using all of its power and a full conditional amendment at its back. The war on drugs has also similarly failed. China has the most power of any country in the world and they cannot stop capital flight or transactions they don't approve of. If the two most powerful countries can't do it then what chance do the rest of them have?
