We already have a set of laws—the Constitution—that governs which laws Congress is allowed to pass. What’s more, not only does the Constitution categorically blacklist certain laws (e.g. the Bill of Rights), it also specifically whitelists the limited set of purposes Congress can pass laws for (e.g. Article I, Section 8). And the Tenth Amendment makes clear that the federal government has no powers beyond the ones explicitly delegated to it by the Constitution.
