> I really can’t think of a less inspiring goal than playing “advanced” or “technically challenging” music
Really? You can't understand how aiming to conquer a highly technical and musical piece is inspiring? It's the same as tackling any other difficult goal.
Music at a less technical level isn't meaningless, but it's an inherent limitation on your musicality if your repertoire is limited by technique.
Technique facilitates greater musicality. Sheet music facilitates greater technique.
Regardless, do as you please, but it's like saying, "I'll never learn code, because I can build no-code products!"
