The important component of Ethereum network - decentralized storage solution : Swarm was released. This is about what you talked.
Today, I have to say this post is a really good idea in 2013 with much forward-looking at that time.
The biggest problem with Swarm and other decentralized/distributed storage (such as Storj and Sia) are they're tied to specific cryptocurrency and limiting who can use them.
Another protocol such as IPFS is more practical and already more popular than Swarm.
