Earlier quoted context omitted.
> Meaningful art is not mass-produced, generated content. Andy Warhol might disagree [1] (: (I realize that's not exactly apples-to-apples, but y'know.) Or there's "art is anything you can get away with," which I just mention to point out that this kind of issue ("what is art?") is not new. In some ways it seems like a good thing to get people, like you, riled up about these topics, arguing the merits of their point…
I don't think that example applies at all here. The quote you quoted itself said it - "subjects for high art". Theres a difference between treating the banalities of life as SUBJECTS for your art and making human, non-mass produced art from that ( like the paining you linked) vs just treating the soup cans themselves as art. At least that's my interpretation of it
Perhaps a more apt example would be Duchamp's "Fountain" (https://en.wikipedia.org/wiki/Fountain_(Duchamp))
