I suspect it is backwards including the source of the doctrines. Precedent while it may have a function in consistency is just gussied up rationalizations essentially. Representatives in matters of disputes would always have a purpose but only a codified law with its complexities would create lawyers. They like doctors also occupy the "high stakes license" version. Combined with incompetence of council as a reason for appeal it is easy to see why the state and others would have a valid interest in quality standards. Small stakes courts are often still done lawyerless for instance.
