As a streaming industry software engineer: File based streaming is done not for DRM but because of distribution cost and user experience. A segmented ABR video delivery massively decreases CDN costs (which is why Youtube, which is drm free does it). Video startup times, seek times, thumbnail scrubbing, fast forward, clip previews, ad insertion and many other things don't work in a file based experience.
In addition subtitles, secondary audio, descriptive video, and multi-view video etc. are all things which we mandate by law which do not work well in a file base expierenced.
Peer to peer as a distribution method is not only know, but there are plenty of providers that use peer to peer like streaming setups (see https://streamroot.io/streamroot-dna/). You may be using something like BitTorrent and _not even know it_.
Distribution is 1/10th the story and DRM is only a small part of it as well. BitTorrent does nothing to solve the other 9/10ths and removing DRM doesn't either.
