"As I see it, it is really pointless to insinuate that great chops are anything but a plus for a musician".
I'd never agree with the notion that technical facility/theory are "detrimental" but if you are suggesting that acquiring these faculties somehow guarantees one will have something worthwhile to communicate or know how to communicate it tastefully, then we profoundly disagree.

"I love complexity and high levels of musicianship in the various genres of music I listen to. And, the resulting emotional and intellectual experience they bring about"
This illustrates the degree to which personal taste enters into discussion of this topic. While complexity brings YOU a particular emotional and intellectual experience, surely you realize complexity may not have the same impact upon others, who may indeed prioritize very different "results".
I am no dummy but personally, I do not want to be "in my head" when listening to music. I want to be emotionally and physically engaged. Different strokes for different folks...
