AFAIK Newpipe is mobile only, so I don't really see how that'd work.

P2P is great on desktop computers (and, in the modern age, Smart TV boxes), where your network connection has no data cap, there are no battery concerns, you're unlikely to be behind CGNAT (common for cellular data connections), and the app can surreptitiously minimize itself to tray instead of closing itself outright, making you an unwitting seed.
