hmm... I understand your frustration with the misuse of the term, but pondering about your question, I've thought of a few examples of consumption of art. besides the most obvious forms such as gastronomy, I thought of jokes that are funny only the first time you hear them, various stories and movies that people enjoy more the first time, some puzzles... in general, forms of art or specific artworks that intend to evoke emotions that are not repeatable, either because they wear off or because we learn (if the distinction even makes sense) are "consumed" by experiencing it. other forms of art are experienced in different ways. and some individuals develop relationships with certain specific artworks that counter the "decay" of "consumption"
