Truly, go live in the real world of being an artist who's struggling to get by at even a basic level and doesn't have all the soft cushions in life that provoke absurdly rigid and privileged sentiments like the ones you wrote here.
Creativity and the desire to express it don't put a person outside the essential pressures of economic need and its emotional roller coasters. On the other hand, when those needs aren't really satisfied, it can quickly become damn hard to be creative even if you're sincerely emotionally passionate about your creative expression. It's nice to spout crap about how people shouldn't create art just for "capitalistic greed", but for someone straining just to pay monthly rent and basic expenses, there's nothing greedy about having their creative motivation lubricated along with some decent sales or financial sponsorship. What nonsense to assume otherwise.
