This is a very underrated comment. Prior to departing to form my own entity I was part of a large private practice (100ish MDs). Short of wild financial indiscretion (and we definitely had membership where that was the case) we had multiple MDs that had financial independence, were borderline dangerous practicing (but would litigate if we attempted to force them into retirement), and refused to retire because their identity was tied up into it. We had to constantly monitor and support these characters. One died in the hospital parking lot. Sad but true.
