That the world exists only to satiate our appetites is practically a founding doctrine of consumerism. That kind of "human exceptionalism" actually degrades man and reduces him to a mere consumer and then corrupts him and renders him an obsessive, exploitative, perverse, and disordered creature, a voracious idiot and a pathetic disgrace. If you want to live the good life, you must respect human nature and its inherent end(s). Dismiss ends, and not only do human beings unravel and become unintelligible, but so does everything in existence. No bespoke delusion engineering here.
