It's a bit more circular than that. The music you were raised with sounds good to you, which means you want to understand how to make music like that hence the dominance of 12 tones and major and minor scales in Western music.
But also, nobody bothers to talk about this because for beginners without sufficient focus on mastery by copying other people, they're generally not going to be able to do anything notable with music anyway, so this kind of meta-theory is an unnecessary distraction. (And by the time you are actually decent with music literally years have passed and you've probably stumbled upon this idea by then)
