I lean more towards he’s looking for affirmation to be contrarian just for the sake of being contrarian.
If he was looking for the best ideas, he would of had a completely different set of guests.
Then how can you honestly believe he's just looking for the best ideas?
This is the same way John Stewart and Stephen Colbert hid behind, "I'm just a comedian." It's a great strategy if you can pull it off.
What's scarier are the persons who for the law are considered entertainment, but conduct themselves on Fox as if they're real journalists, and lie and deceive with impunity. If Joe Rogan could disrupt the right media with that, the same way John and maybe Stephen did on the left side, the world would be a better place for sure.
I’d say a special mention in the first amendment is notable.

Rogan feels like he wants it both ways. He wants to pick the people for his show and get credit when he picks well, but if people dislike one of his picks he would suddenly like to be seen as 'mixing it up' or a "cage fight commentator." He won't really own a view (or the idea of wanting to expose people to particular thinkers), but he would rather bring people on in a way where he's seen as minimally responsible for the uncomfortable content he produces.
If he was just some random dude none of this would matter. But with 11 million followers, sometimes this "my youtube research is just as valid as your scientific research" attitude can do real harm, as it did with vaccines.
The more you claim to be the one to take seriously, the less serious anyone will want to take you. Especially if you do it in a negative fashion blocking others rather than putting out your own message. There's far more to influence, trust, and authenticity than claiming you're right or deducing everything to some rational puzzle, and perhaps that's the biggest lesson of all.
