“OK but there are also plenty of times where a yachid reveals a chiddush which is a valid path in Avodas Hashem. Shivim panim laTorah”
Which Gedolim (past or present) are on record endorsing that a Rebbe is mahuto v atzmuto mamish areingishtelt b’guf ? Can you cite a credible example of even one?
From your posts it is clear to me that you are a sincere person. You know very well that the objection to this chiddush is not only from one Gadol. I’m very surprised you would claim such a thing.
“Also it seems to me, although I could be wrong, that there is a halachic “due process,” like by the gemara they hashed out their proofs for their opinions, and then voted on the final halacha.”
There are many examples post chazal where there is closure in halacha and dayos. For example:
1) Turning on a incandescent light bulb is chillul Shabbos
2) The Zohar HaKadosh is authentic
