I mean, if you apply this same reasoning, then "eating this big mac is extremely necessary unless you have one of these weird genes that makes you not crave these type of foods" becomes also a valid argument. It's not about what humans feel they need, it's about what they can live without without tearing their lives apart.
Not analogus at all, there's a wealth of consumable objects other than a Big Mac to sate your hunger. Setting aside fetishism, there's really just one object that sates sexual drive and that's a human being. Or do you think a sex doll is an adequate substitute with no second-order effects?
Me wanting to be famous can only be satiated by other people considering me an enjoyable person. But would you consider that I would be unhappy if I failed at being famous?
