alt Hacker NewsIt doesn't sound like you're refuting the central claim. Artists still have to be concerned about marketing, sales (i.e. I made great art, but now need to find someone to buy it if I want to eat), revenue, profit (i.e. I made money, but if I spent more than I made on materials then I didn't actually make money), and so on. It's a business.
What you're highlighting is that art's value proposition is different from the value proposition of typical businesses. But not that artists are somehow free from having to worry about basic economics.
It's not a business. Selling art is a business. Making art isn't a business.
Many artists would rather blow up their careers than make work solely for business reasons.
There's a huge cadre of content creators and entertainers who are happy to do that, but - as the previous post says - their work is typically entirely forgettable. Even when it's commercially successful.
And successful original creators usually have business managers to deal with "basic economics."
The ideal for most artists is complete creative freedom and an open budget. Not many get there, and not everyone who does get there produces something memorable. But it happens occasionally, and it's usually far more interesting than create-to-market content.
