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
I agree it's not a perfect parallel. But it was very much part of a movement that challenged traditional notions of what art was, and spurned similar debates and outrage as here.
Perhaps a more apt example would be Duchamp's "Fountain" (https://en.wikipedia.org/wiki/Fountain_(Duchamp))
