The article makes one incorrect assumption, that there could be enough redundancy on a peer basis to make reliable p2p storage, rather than requiring each shard to be stored in a different country, making centralization of resources impossible algorithmically. Storing data in one country is a huge risk. One thing is probably true though, the number of countries will likely be limited to those, where providing storage is most economically viable.
