For a lot of people "what you can do" is the vehicle that gives them the means to work towards their accomplishments. Congratulations to you on being at a point in your musical development where someone like Robbie has nothing to teach you. I'm sure there are bass players who aren't as accomplished as you who could benefit from Robbies knowledge and experience (as limited as that may be).
That's a pretty good point. Another thing that occurs to me after considering your post is that it wouldn't be practical if only the best of the best taught, there are probably too many students.
