Oh yeah, I forgot artists are spiritual creatures who don't have to eat. It certainly isn't the only reason to create but a necessary condition to actually be a professional artist, no ?
Why don't you just ask for an increase in the allowance from your family trust fund? People have become so lazy nowadays, they can't even be bothered to have a hard talk about their financial estate with their rich grand-papá anymore.
Also, patronage is garbage, in my opinion. It ensures artists are exclusively either already wealthy, or well connected. It also helps ensure that the wealthy are most often represented in the art created; for some reason this seems like a bad idea to me.
copyright based scarcity is effectively dead for anyone with an Internet connection anyway
honestly I think a gratuity model may become dominant with or without any legal changes at this point
you'll often see on YouTube patreon revenue equally or dwarfing ads
the reliance of the music industry on merch seems similar too*
I think people are more willing than you'd think to pay for art simply because they understand it won't exist without money.
*(if that sounds like a stretch, consider if in a world devoid of copyright, whether a Walmart printed band shirt for cheap would be equivalent for most purchasers to the same shirt sold by the actual artist )
