This would be theory done wrong.If you learn theory, you are taught how it's SUPPOSED to be done, and you feel bound by those rules. If you don't learn theory you may simply do what comes from instinct, with nothing to bind you. Someone who is used to the freedom of instinct might suddenly find their creativity hampered when learn that they're "doing it wrong." Others might feel this helps them. Again, it's up to the individual.
Theory done right is when you learn how to make your music sound exactly the way you want.
Which would be the only point of spending time learning something
Does your music already sound exactly and precisely the way you want? If it does, you don't need any help. If it doesn't, you have something to learn -- so you can fix that. You should be your own favourite composer -- are you?
In your defence, theory is usually taught the bad way, so I understand why you think this. This includes the vast majority of books, courses, and even some theory I've seen touted on this forum.
