I don't understand your arguement sir. I have no 'theory' All i got to say is open your mind up good music comes in all forms. What may seem like simple "rhyming of words" is actually pretty difficult to do properly. Obviously the nursery book rhymes are the easy part, but putting together concept songs that deliver messages and making it all rhyme (and sound good on the beat), sometimes multi syllabic rhymes......this takes talent. Being able to sound good over a beat takes practice to perfect it. It's only the garbage rap you find on mainstream that brainwashed you into believing that rap is a useless and simple art form when it's actually a deep thought provoking art form when well done and the songs have long hours put into the writing process..You gotta realize sometimes there's more to something than what meets the eye.
