If you read some of the original documents about the web, you'll see that it was one of the ideas. It never made it further than being an idea though. Although IPFS seems to want to implement something like that, and probably much easier to do in a content-addressable way (like IPFS). So content has a hash, and as long as you trust the source of the hash, you can download the content of a hash from anywhere, even your drunk and slightly annoying neighbor that you don't actually trust, because you can verify that you got the right bytes after all. Bittorrent does it for transfers already, and it works alright, so why not for the web too?
