The point is that traditions, especially long established traditions, generally do in fact contain good advice.
I think the point is weaker: long established traditions do not contain self-destructive advice and contain good advice for the times in which they were created. If the circumstances have changed sufficiently, the advice of ancient traditions could, in fact, be bad.
