Moshe Rabbeinu

That he is called Moshe Rabbeinu was, in the past, understood as a way to make the rabbi the political leader. Another way to read it, and, I believe, the more accurate way, is to understand Moshe as not the leader but the partner with YHWH about the functioning of the mitigating institutions. He is Rabbeinu because he was not one of the nessi'im, nor was he a kohen. He was the one who designed and erected the institutions that protected the civil society rather than trying to design the primary institutions of markets and governments.
