https://github.com/nostr-protocol/nips/pull/345 is pretty ingenious and simple, and could be a good thing, even though I agree with all the criticisms it has received too.

But personally I don't understand why we can't just use torrents. BitTorrent already supports "webseeds", which are servers that literally serve the file, and the same file can be served from many of these servers. BitTorrent is a very simple protocol too, with many libraries and implementations in many different languages. There is no reason to reinvent things.

Or maybe there is. What is the reason? What can this (or other similar proposals) do that BitTorrent directly can't?
