That's an interesting question. I'm not sure. We sort of had that one-stop shop experience with Netflix's DVD service, where you would pay a subscription fee and in exchange you would get to watch movies from a huge catalog. But this didn't translate to the streaming era.

P2P film piracy, at least for the quality-minded, has a few strong competitive advantages over film streaming. It doesn't have to deal with rights issues, for one, which can present huge roadblocks to film distribution. Films are also huge files and the interests of a streaming platform (low bitrate) are in tension with interests of quality. Even in comparison to physical media--the highest quality release of a film might be from a different market than yours, or there might be many competing releases over time. There might be different factors that are better in one release and other factors better in another release, where the pirated copy can combine all the best parts. It's actually somewhat remarkable how good film piracy has gotten these days for those who care.

I don't think quality is really much of a concern for the majority of people, only enthusiasts. I suspect, analagous to 128 kbps opus (on youtube music), most people can't really tell the difference between a 1080p bitstarved stream and a 4k bluray rip.

The library for the music streaming platforms is much bigger than for films, of course (about 250 million for Spotify), but there's also a much lower barrier of entry. So perhaps the higher work needed to produce a film necessitates more profit, to a degree that only the fragmented streaming platforms can fulfill. After all, netflix started making originals to counter studios launching their own streaming platforms to raise profit margins, and pulling their content off netflix.
