The best answer to this I've come across is the idea of a P2P web (ala Bittorrent). If the assets are hashed then every version of a website (potentially) would be out there for you to retrieve. Then Archive.org would actually just be another P2P node to help guarantee content from becoming peerless. I honestly wish sometimes we could re-architect the web to use P2P instead of point-to-point communication. It would be a lot harder to censor for a start.
