Many people, including myself would argue that we should not try to blindly maximize our evolutionary fitness. Yet, blindly following hedonistic preferences by indulging in superstimuli also seems questionable. Maybe there is a ideal middle ground, or maybe there is no consistent position.

It's not a one-dimensional spectrum with evolutionary fitness on the one end and blind hedonism on the other end in the first place. Your evaluative psychology just doesn't work that way. As to why you think there exists any such spectrum or trade-off, well, I blame bad philosophy classes and religious preachers: it's to the clear advantage of moralizing-preacher-types to claim that normal evaluative judgement has no normative substance, and that everyone needs to Work For The Holy Supergoal instead, lest they turn into a drug addict in a ditch (paging high-school health class, as well...).
