I’m arguing no such thing. Artists can, but don’t always, choose to be generous with the product they make, just like bakers sometimes give extra loaves to homeless people. Would it be true to say that free food has no value? In either case it’s an act of generosity. Bakers and artists can both choose to set whatever valuation/price they want on their work, and can adjust if their chosen price point doesn’t make enough sales for their goals. It so happens many artists already have enough money, and simply want people to enjoy their work, or spread their name. The vast majority of artists don’t have enough money, hence the sardonic meme of the starving artist.
