Maybe that's your opinion and the perceived opinion right now, but your claims directly contradict what many successful teachers state. (But see below, maybe we don't disagree.)
In Germany, for instance, there used to be these little "ETP books" for guitar players called Tägliche Übungen zur Entwicklung einer Technischen Perfektion that involved lengthy and absolutely monotonous finger exercises that really had nothing to do with music. Everybody praised them and everybody said that these and similar exercises are essential to become a world-class player. There is hardly any way around it, they said, you cannot become that good by merely playing music. I still have no reason to believe they were wrong. It would be surprising if arguably harder instruments like classical piano didn't involve similar monotonous exercises and the same couldn't be said about ballet, world-class athletes, etc. A friend of mine is a professional jazz saxophonist and while he was studying saxophone he had to practice scales up and down for hours and hours every day.
You've got to put some serious effort into it, you agree with that, right? So maybe we agree in the end, because you use vague word "engage". Of course, nobody denies that you need to find a way to motivate you to get through these exercises or to stay "engaged". I didn't deny that. All I'm saying is that a lot of "mere repetition" is needed in many disciplines in order to reach a really high level while staying motivated.
Extensive practice is essential to getting one's self to the point where creativity can take over, where the muscle memory can 'meld' with one's expression of whatever emotions are being communicated via music.
There are certainly counter-examples, musicians who compose from day one, and don't really focus on melodic theory, running scales, and all of the other pieces of the neuro-muscular puzzle that go into making one technically 'good', and some of them do well.
There are those that allot all of their time to becoming technically proficient, pianists who spend endless hours working up Rachmaninoff's 2nd concerto, only to get so lost in the technicality of their discipline that they become cold and mechanistic, but, again, are so proficient that they find work their entire lives.
But true greatness needs both. You have to, as one artist put it, be able to 'forget' all that you have learned and compose and/or perform from the heart, letting all of that training do what it will naturally do, resulting in a transcendent expression of artistic grace.
That's what makes Campbell so accessible. He speaks and writes as though he is talking about the weather to his best friend, but his erudition provides such a solid foundation in the topics he expounds upon that one hardly notices that one is being educated.
