"By definition, art should be free".... what definition? Your definition?

There's been private art since forever you're just angry your favorite artist paywalled their work for something like 5 USD so they can make a living out of doing something they like.

Let's assume all artists have to share what they draw for free, you think you're gonna get more art? Wrong you're gonna get way less and what you get will be much lower quality because I assure you no one will ever want to put a lot of effort into learning a non-profitable skill like drawing.
