Sure, someone is going to need to write the firmware for the machinery in factories regardless of copyright protections, but who's going hire animators if they can't sell the final product or monetise it in any way without immediately competing against their own work? People who make commercials? Real bright future you're depicting there.

But more importantly, aren't you forgetting something fundamental here?

I’d rather not live in a world where art is economically unviable.

This is not just about the artists, it's also about me. And by me, I mean everyone, including artists, because they don't just create art. Most of the art I enjoy is mass-produced: books are, films are, video games are. If those become economically unviable in the current economic system, then my art appreciation would basically become occasionally going to a concert or museum, and going through humanity's backlog of works. Certainly, that backlog is large enough for many lifetimes, but while Cold War analogies are still relevant to some extent, it sure would be nice to enjoy something that speaks of today every now and then.
