There is a huge, sprawling market of art online. And I don't mean stuff with the cultural approval of the gallery system. I mean, say, people making a living by drawing mind-control commissions on Deviantart. Paying the bills by cranking out custom art of folk's furry characters on Furaffinity. Selling commissions of weird stuff via Tumblr. Folks doing web comics and selling ads/books/t-shirts. Custom clothes/jewelry/chainmail/whatever on Etsy. Patreon is helping too - lotsa people are starting to say "hey I just wanna draw some COOL STUFF and if you like my themes then help support me doing it" in various ways on that site.
This economy has been booming ever since Paypal made it easy to give someone money online.
None of it is "Fine Art". No small amount of it is pornography. It is not glamorous. It is not pretentious. A hell of a lot of it is amateurs still learning. But there is a lot of it, and some of it is amazing.
Seriously: I have a friend who put his wife through nursing school, and is still helping to support her and their child, by drawing outrageous furry latex bondage commissions.
