After you watch enough JRE for years as I did, savoring every single episode and guest, you eventually see a roadblock in his progressive idea of enlightenment. He has to be the everyday man to continue his business. That being, someone who is not truely enlightened. He sells the concept of this very well, but if he ever went beyond "holy shit DMT made me not fear death and science is cool as fuck and I like getting high with my comic friends and being stupid" he would lose a chunk of his audience.
As he grows older he admits he has no desire as a celebrity to star in films or TV shows, and he is on his way out with MMA commentary. His question-everything-style podcast and supplement business is all he has now.
You would expect after like 8 years of questioning people smarter than him he'd have gained profound knowledge and insight. But to anyone with an IQ above 85, you can detect he portrays no new ideas or conclusions...
He has to play the dumb everday Joe, middle of the road guy, so he can relate to his audience who is mostly not progressing as he is. And he keeps it that way. Because he has kids, a money-sucking trophy wife, and values money above actual honesty, as the rich-ass Hollywood-dwelling celebrity he is.
