I think it's actually rational to say that you think it's good for the world and for society for people that are compelled to do art and skilled at it have an avenue to make money off of it (or at least to be recognized for it), and to therefore choose to vote with your wallet for bespoke creators to prop up the industry.

In the same way that you could rationally choose not to shop at Walmart, even if it's superior in price, quality, and convenience, because you want non-Walmart stores to continue to exist.
