True. But it is still easier in many cases to pick good experts than to independently assess the validity of expert conclusions. So we might make more overall epistemic advances by a twin focus: (1) Disseminate the techniques for selecting reliable experts, and (2) Design, implement and operate institutions that are better at finding the truth.
Note also that your concern can also be addressed as one subset of institutional design questions: How should we reform fields such as medicine or economics so that influence will better track true expertise?
