How feasible would a reliable, distributed archive be; given how massive amount of data Archive.org has? After all, it was created precisely because the already-decentralized web was too ephemeral and unstable. I don't think decentralization is a panacea in this case.
Some problems are best solved by institutions.
The way to solve this is to provide the Internet Archive with enough resources to build out a globally distributed storage system. Could you hack something together using their torrent tracker for every item served? Yes. But you don't hack together something made to preserve digital human culture in perpetuity.

Yeah, I agree. I do see a space for other appropriate institutions (such as the Library of Congress, British Library, etc.) to pool resources and facilities with the Internet Archive to achieve that goal.
Ultimately, it'd be awesome to see each national library run a semi-autonomous IA copy that synchronizes with all the others, but can continue to operate independently (scrapers and all), if need be.
