It is interesting though, what happens if you put so much data into a blockchain. I guess only a couple of nodes would want to verify the validity of the chain (because you need all the data to do it). And would those nodes really be more likely to keep the data then the situation we are in now? I guess after some time the nodes would agree on the hash and throw away the data because it would cost too much to store.
