I'm not sure that it is necessary to consider the laws of physics a separate
ontological category. A zoologist might study the behaviour of chimpanzees,
take notes, and summarise these notes in a paper for others to read and test
by seeing if chimpanzees do indeed behave as claimed. The "rules of
chimpanzee behaviour" is not separate to how chimpanzees actually behave nor
does it have any causal effects of its own. Similarly, a physicist might
study the behaviour of electrons and write a paper for others to read and
test by seeing if electrons do behave in the way claimed, but these "laws of
physics" regarding electrons are not separate to electron behaviour and have
no causal role in electron behaviour. Electrons and chimpanzees behave in
the way they are inclined to behave, and if we can discern patterns by
observing them, that's just our good fortune.
