True, this needs to be addressed before I can get what I want. In the case of media it's got to be either on-chain or strongly coupled so that once published, an artifact remains available even if comparable artifacts are produced. It probably won't happen top-down, media giants are keen to keep their content in their walled gardens. Journalism might be a good fit to start with.

This seems like a substantially non-trivial problem to solve: hosting files is not free — think about how large a film is even with modern compression — and most copyright holders are concerned with preventing unauthorized copies.

A long-term durable copy requires ongoing money storage and transfer costs which have to come from somewhere but most people aren't going to pay to host something they can't use (due to encryption) or already watched / copied, and anyone trying to sell content is not going to use a service which allows unlimited unpaid distribution.
