There are two concepts of the scope of a law: 1) the set of bodies (in our world) in which the law is fulfilled, 2) the set of models of the law, or the set of possible worlds in which it is fulfilled. Their use leads to opposite answers to the question which law is broader than the other.
There is one fundamental and many non-fundamental kinds of existence. Things (material bodies) exist fundamentally. Many other objects exist non-fundamentally: properties, events, relations, states; abstracts (universals), laws of Nature; possible states, virtual particles; minds, mental processes; ideal objects created by minds (Popperian "World 3"). All of them are always based on material bodies, but they exist really.
