Then why do you need a host at all? Why even have journalists? If as you say listeners and viewers are perfectly able to get the truth out of speech, wouldn't the best to only have direct unfiltered speach with nonody in between?

The host provides an available platform to an audience. If I was a guest on a Joe Rogan podcast, I can be certain that some non-trivial amount of people will hear me. If I make my own one-off podcast and upload it to soundcloud, youtube, thepodcasthost, whatever, It is close to assured that I will have a lesser audience, if not close to no audience.

Joe Rogan's platform brings listeners to a topic, not to any specific opinion.

Not really. The host serves a purpose to proke and prod the guest to direct and dissuade the flow of conversation.
