I don’t like the Mona Lisa, but this is shortsighted. I agree that more people would tend to generate more instances of good art, it has nothing to do with the tools or the technical aspects. The point of art is beauty and emotion. Better tools do not always help and in fact modern art is often famously opaque and inaccessible.
> The only reason people pretend to like it and most of the rest of the 'fine art' is an emperor has no clothes schtick, a sort of snobby cultural pressure where everyone has to act like it's so special and good because that makes you cultured
It’s all subjective. People liking something you don’t does not make them brainwashed, and it does not make you better.
If you are genuinely interested in this, you could have a read at this https://dynomight.net/bourdieu/ . It’s a bit more subtle than you say.
