We are not talking about music. Music bands can sell less disks, then loss that 2% of the share they get (98% goes to the publisher, 2% to the musician), and get 40% of the concerts with pirate fans. So for musicians it may be good.

We are talking about 3D works. It takes a lot of work, knowledge and research to learn and make them. And we have no other source of income. I can't make a concert of 3D models :) So don't compare these situations, they are not related.
