I'm gonna straight up disagree here. All your points are mislead. There's math in music, but music isn't just math.
A quick example. If you listen to contemporary GenZ music, you'll notice a ton of extremely happy songs, that are in minor scales. This usually trips classically trained musicians because, well, major = happy, minor = sad, was the science for the past 400 years. However, this is not a natural imperative, it was a cultural quirk of western musical tradition. Contemporary pop, is doing away with it as younger composers and producers experiment with modal theory and unorthodox rhythmical structures and find wild commercial success with younger audiences.
Then you have some young bands like Angine de Poitrine (of recent viral fame), that just flips over your arguments by making microtonal polyrithmic music that is perfectly scientific and mathematically organized yet it sounds alien. Music is art, get over it. If people likes it, science has no power over it. Music theory is, precisely, just some relic of colonialism.
