A fair criticism. Personally, I've spent enough time around folks who followed their passion and seen where it got them that I'm 100% on board the utility function train.
Utility is fine. Packing shelves is fine. Do you have time to follow your passion out of work? Can you make your passion pay enough? Most people I've met who gave up on their passion seemed to want praise, fame and/or notoriety rather than the 'art' or whatever they were producing.
Somewhere in here there's the Peter principle that people rise to their highest level of incompetence... it's true in art as well as engineering/business.
Utility for the win! Following your dreams is fun and all, but the risk/reward ratio is just way out there.
