I love P2P and I have been into it since the Napster days but it isn't feasible any more. The value of a random Internet device is actually negative because the complexity of wrangling it outweighs what little resources it could contribute. (See Spotify and Joost for examples.)

I assume all these decentralized storage systems are datacenter-based so I'm comparing random Chinese datacenters vs. FAANG datacenters.
