Some types of work would definitely survive in a copyright free universe. But many wouldn't. You wouldn't have full time authors. Musicians would mercilessly rip off each others songs.
Forget about tv, high budget video games, movies, etc. That stuff takes serious investment to make.
>Musicians would mercilessly rip off each others songs.
This is a ridiculous claim. DIY and free music culture has made a lot of unique stuff. Have you heard of the band "Bomb the Music Industry!"? That was their whole thing. Musicians already copy each other in general, but the problem would not get worse.
