> 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.

Again, you're arguing a distinction which the author agrees with. From the article:

> Most people who enjoy making art should not try to make it their full time job. When you turn an avocation (hobby) into a vocation (job) you have to do new things you do not enjoy.

I think perhaps you're getting hung up on some semantic quibble rather than focusing on the broader point. "Artist", "professional artist", "artist for a living", "someone who spends most of their hours making art but also needs to eat". Choose whichever term satisfies your complaint. These people need money to live, that's just how the world works.
