Like I said, I agree with you. It doesn't fix anything, but it could help, because of the service it provides.
As for the service itself, and from a consumer point of view it wouldn't be any different from a regular streaming service. Yes, there would probably be a coin associated with the platform, but nothing really special there, as for a consumer, just a way to "pay per view" the content would be enough, and they probably wouldn't care if they were paying with crypto or fiat.
I do think that for the content creator (either a team, or a individual), being able to share their content in a decentralized platform could help for the normal reasons usually associated to blockchain. No need for a middle man (like Apple on iTunes for example), so this would probably mean bigger gains for them.
Also, and I'm not sure if this is possible though, I guess that getting the content just available in that platform could probably help as well. Of course that anyone would probably just record it, as they do in theater movies, so no real advantages there. Although I do think that piracy gets easier when the content gets available on other media formats like DVD, Blue ray, etc. Don't really know what kind of media sources pirates recur to, in order to make the content available illegally on torrents, etc, but maybe something could be done here as well.
