If chefs were to expect that people must use high end ingredients in their cooking (or top quality kitchenware), then it tends to exclude the cooking efforts of those who can't afford, find, or even regards those high end ingredients (or kitchenware) as essential. (Not to mention potential diet restrictions.) I also don't think that these people should necessarily be aspiring to possess those better ingredients either simply for the sake of possessing them. It seems like the fundamentals of cooking the dish are more important to learn and perform. I don't think the conversation is about disregarding the quality of the ingredients (or the wordcraft), but in recognizing that buying quality ingredients is not essential for cooking the dish. It's a luxury, and I don't think we should shame those who either can't afford or choose not to cook with those high quality ingredients.
