Bat Kol as an autonomous value arbiter

As is known, there is a disagreement among the Rishonim (Ramban and Rav Hai Gaon) as to whether to go by the quantity of the judges or the quality of the arguments. There is also this disagreement among the Poskim. Some even wrote that this is a disagreement between the Shaykh and the HaShem.
The voice of the voice decided according to the Lord. Hence, it seems that the majority does not reveal the truth, but rather it is the rule of conduct. And you have already written about this in the past, rejecting it, etc.
Now I thought, in light of what you said elsewhere, that the purpose of halakha is twofold: A. Revealing the truth. on. Autonomous value. Perhaps Bat Kol decided that autonomy is preferable to truth. Therefore, since most people thought like Beit Hillel (they were the majority), the law was established like them. And in fact, what is written here is that autonomy is preferable to truth.
