There is no technology possible that removes said responsibility. This is how peer to peer systems work. Your criticism is something that no peer to peer system claims to solve.
Actually, I recommend you check out Freenet [0], a project that's 20 years old. In fact, the Wikipedia page explicitly states:
> Information flow in Freenet is different from networks like eMule or BitTorrent; in Freenet:
> 1. A user wishing to share a file or update a freesite "inserts" the file "to the network"
> 2. After "insertion" is finished, the publishing node is free to shut down, because the file is stored in the network. It will remain available for other users whether or not the original publishing node is online. No single node is responsible for the content; instead, it is replicated to many different nodes.
Aren’t collaborative systems like that susceptible to abuse? E.g., an attacker could upload 1TB of noise and then shut down, reducing the network size by much more than 1TB.
Not really, if you want something to be perpetually available in any p2p network you need to ensure that you're still hosting it. That goes for torrents, ed2k, freenet, and ipfs too.
It's possible for sure, but with Bitcoin and the overall crypto space steadily growing in value into the trillions over the course of over a decade, it seems unlikely.
