You're not really responding to the parent. Yes, people can and will create art with no profit motive, but some people are considered really good at creating art and make their living off of it. In the yesteryear before the Internet, selling artworks was effectively the same as selling other products; you get a physical item that you keep. Now there are all sorts of issues with copyright, and while I don't support all aspects of the copyright system, I also don't think that artists should be thrown to the curb. You would probably care if you wrote professionally and computers were threatening your livelihood.
