having good technique has nothing to do w/how long you've been playing, how vast your repetoire is, or how much knowledge of the fingerboard you have, and can not be spotted in a recording.
I was playing for over 10yrs, had several different teachers and was in my second year of college as a music major when a former teacher helped me revamp my picking technique making me 10x the player I would have ever become. Having good technique will take the frustration out of playing and will enable you to play what you want too when you want to. No more "boy, I hope I can pull this solo or lick off tonight". As I'm sure you know. I see a lot of validity in what your doing I'm just pointing out a few disadvantages.
I would also miss the spontaneous jams and the intellectual exchange of musical ideas that can only occur when playing off of someone.
