BitTorrent then, under this perspective, is "less massively, less redundantly replicated" since people only hold onto and seed the torrents whose files they store locally, but they do not just go on and download and seed everything out there. Seems like a nice compromise to me, but obviously risks data becomming irrevocable in some cases. Is this also how IPFS works?
