In "the hitchhiker's guide to the galaxy" there is a story about a society that shipped out all its useless members (hairdressers and telephone sanitizers) off planet. If Douglas Adams was writing the book now he may have replaced sanitizers with influencers.
I think you vastly underestimate "influencers". Just replace that term with advertisers, because that's exactly what it is. Everyone is looking for the new advertising paradigm? You're looking at it. People are ACTIVELY following these people, and enjoying it.
I think you are wrong, they are more rock stars or sports celebrities.
