Agreed! Although i will say i believe you are meaningfully contributing to preservation when you permaseed torrents, especially in private trackers. These are geographically distributed copies available for others to grab and contribute to keeping safe.

Obviously not to the degree of long term professional archiving but I do think it is a form of preservation to a greater degree than an average home user doing 3-2-1. The greatest risk of loss comes from people not resharing all their content when the private trackers disappear.
