Artists don't get paid, piracy or no-piracy. The middlemen get the majority of the profits in the MPAA-protected mafia industry.
Putting tools in the hands of artists that provide them with the ability to contact many, many fans, and be assured of that relationship without interference by a 3rd party, is quite a valuable goal. Thankfully I'm not the only one with that aim.
Like I said, artists could already bypass the MPAA-protected industry and get a much larger share of the profits and direct contact with the fans by setting up a site as I mentioned before.
If they don't even do that, I think it's unrealistic to assume they'll start using IPFS and host their own stuff.
