If that were the case, he wouldn't have the massive following he does.
His followers follow him because he reinforces existing points of view. Nothing wrong with that, just saying that having such following doesn't imply original ideas.
I recommend the "what is true?" making sense podcast episode (https://samharris.org/podcasts/what-is-true/). It helped me better understand Peterson outside of the spotlight generated by him touching the controversial topics if our society. My opinion on him after that interview is even less flattering: he seemed interested in bending terminology and logic itself for the benefit of crafting a worldview he deems innate to humans, instead of researching our nature though inquiry. The feeling I got was that of an erudite anti-scientist.
In particular, the anecdote about how Peterson wanted to be a preacher.
Where might a person acquire such knowledge? It implies that someone would have had to compile all of JP's ideas, and then compare it against the knowledge of all Westen people. That sounds like quite an undertaking.
Every single idea he has is conservative orthodoxy of one kind or another. Nobody living in the Western world has been spared exposure to the ideas he is so in love with. He is just good at failing to explaining them while being as un-concise as possible.
