Why can't goverment DMCA requests work for blockchains? How is your suggestion much different than bittorrent? The goverment could just as easily take down links to the blockchain as they could takedown links to a torrent. Exchanging trackers for pow isn't a real advantage. Especially for large datasets (Youtube) where a third party will have to index the blockchain for reasonable to access it.
