Can propositional logic exist without a set theory?

You can't swipe your hand and make set theory go away. Asking about what happens in a world without set theory is meaningless, because there’s no such world. It just doesn’t work that way. So I’m afraid the answer is negative - there’s no propositional logic without set theory, because there’s no world without set theory.
