Then we shall return to the times before the 19th century, when people created art because they loved art, not to get rich. I suspect it will lead to higher quality art, even if the quantity is lower.
What nonsense. I don't think there are many musicians today who don't love art. The problem isn't just being unable to get rich, it's being unable to afford to be a musician at all, and that was certainly not the case before the 19th century (there were plenty of paid positions for musicians).
I believe all that would do is make wealth or extreme tolerance for poverty a requirement to become an artist.
I think artist will have to focus more on cultivating a strong fanbase globally and leverage it for merchandise and live performances. There is lots of money to be made being an idol.
Go read about YouTube or Twitch burnout to see what happens when artists are forced to go that route.
You mean artists should do ads? I find it ironic seeing this suggested here. How do you feel about ad-blockers then?
