If I as an artist make a great piece of art, you don't think I should be compensated for it. If I complete a surgery or drive a truck which all of them are byproducts of ideas and knowledge I should be compensated for them, not just for thinking of them. You see the problem here? I don't want to pay for an idea of art, I want the complete and original piece made by the artist. As for if they generate the art using some machine learning model, they need to disclose that so I can make conscious choice.
