It's probably less about having peers seed videos all the time but buffering bandwidth spikes. Let's say a video gets posted and gets a million views in the first day. That's a lot of load on a server. But if thousands of peers can serve each other the chunks, then the server isn't responsible for all of them. So WebTorrent can provide a level of scalability without greater hardware. Just doesn't mean that most of the videos are going to be served by peers.
