this is what the "gossip model" and the "HORNET Storage" project FOREST protocol are about. gossip is not scalable, it requires all nodes to be equally large and shakes out the small ones. FOREST is demand side and enables an efficient publish/subscribe model that IPFS does not enable (and bittorrent is built on the same math as IPFS).

yes, if this problem isn't resolved eventually it leads straight back to silos.
