And there's no criteria for "ability to draw".
Yes there is. It's, do people want to buy it?
Consider Outsider Art, and an artist like Jean-Michel Basquiat who was widely disparaged in his own lifetime as 'not a real artist', but whose work Untitled (Skull) became in 2017 the highest priced painting ever sold at auction for artwork by an American artist in a public sale. He impacted the art world, and the value of his art has increased after he died, because people are still talking about it, having it influence them.
Vincent Van Gogh never sold a painting in his own lifetime. So his experience was being told that he wasn't an artist, his work wasn't art. But he had a vision, believed in what he was doing and why. His work went on to be very influential after his death, and now by insurance valuation he produced the most valuable body of work of any artist.
If you go back to the Rennaissance painting was considered craft and the real highest art was considered being an architect - which ironically has switched around now, with most large buildings being just assemblies of concrete and glass cubes, with a little flair to the silhouette if we're lucky. DaVinci brought a deep understanding of human mechanics to his work. Michaelangelo, who was also thought to have been observing then illegal human dissections, was deeply inspired by the art of antiquity which the Christian world had largely shunned, and was renowned in his lifetime for artworks that inspired awe in viewers. They did not just perfect their crafts, of working with bronze, paint and sculpture. They altered and extended the ideas of their peer group of artists, then and after, about what could be achieved in their media.
That is how I think we should understand what art is: high craft which shifts perceptions about what effects or ideas can be conveyed. Creativity, with what creativity is. Discussed more fully here: Video games as new art So note, art is not in the objects, or the determination who is an 'artist', but about interaction with cultural discourse, in somehow going beyond the "mediocrity and copying" as you put it. It's easy to dismiss modern art, and honestly most of it will be forgotten. But what is involved in telling the story of how we got where we are with art, that will remain. You know, what would have been a pivotal piece in that story, Duchamp's Fountain, was so controversial at the time it was literally considered trash and discarded. You could say that was the real beginning of Modern Art, the throwing down of a gauntlet with a radical challenge about what art is, and where the limits on it are.
Another interesting case, a comic book artist definitely considered a weirdo in his lifetime:
"Pinajian also painted portraits, landscapes and some abstract works.
He has been cited for his work in the field of abstract expressionism.
Pinajian had instructed that the works be thrown away when he died.
His wishes were ignored, and $30 million worth of his art was found in
the garage of the Bellport, Long Island home" -from Wikipedia
An updated valuation estimates the collection is now worth $90m. He dedicated decades to his painting, living on his sisters money, but never 'broke through' and made any kind of living from art in his lifetime, other than his illustrating.
You say
people who actually do something instead of playing this pretentious
games are discriminated and considered just "weirdos". It becomes kind
of the opposite of art in many ways where only mediocrity and copying
of others is encouraged and taken as a "reference", and any truly
creative endeavors are practically punished by alienation.
You seem to have an implicit fantasy that the art market could or should serve artists. It serves wealthy people, as exotic investment vehicles, and many if not most of the worlds most valuable artworks are in secure storage, not even being looked at. Investors make a gamble based on who's work made waves, and sometimes they support exhibitions and retrospectives to raise profiles of artists, to benefit their investment.
What can we do about that? Tax the art market and auction houses, and use a fair system to allocate public subsidy to promising artists. The same issues exist in music, where a few bands that can fill arenas make all the money and have leverage against the music industry. Creative industries and arts benefit us all, and that should be respected seperately to profit and livelihoods generated.
Go buy an artwork of a local artist, go to local gigs and buy the band's tshirt. That's the most direct way to support more art and music.
