Regarding the criticism of Rabbi Kola's description of the situation at Mount Sinai

In Prof. Frankel's analysis of the tradition of the Mount Sinai status, he claims that the Mount Sinai status is a fairly esoteric tradition in the beginning of the Jewish people and only returns to the forefront during the Second Temple period, and places it as opposed to the prophetic tradition in which the development of divine law was done through individual prophets who were not bound by the Mount Sinai status and a canonical national text, which also allows for the existence of contradictory traditions. It seems to me that this description is consistent with your and Rabbi Kola's dispute as to whether the binding validity of the Jewish way of life can be established only from the Mount Sinai status, or whether an alternative model can be proposed in which the validity is established by charismatic figures with spiritual intuitions anew in each generation. Does the Rabbi accept Frankel's conclusions, and if so, the implications for the discussion with Rabbi Kola? https://thetorah.co.il/article/judaism-without-sinai/
