The thing is, if you were serious about your idea that music should follow the laws of physics and the universe, you would look at those laws and say "ok, what kind of music can I write that adheres to this".
What you're actually doing is cherry picking certain ideas about physics and the universe in order to justify imposing your own narrow vision of music onto others while conveniently brushing aside those aspects of physics and the universe that clearly disagree with your vision of music.
What about the random nature of quantum mechanics? That would seem to suggest something other than Baroque music. What about the harmonic series? Not only does it not suggest equal temperament, but even if it did, it still wouldn't suggest tonality at all, never mind Baroque music. What exactly is it about the universe that suggests a Concerto Grosso?
