I agree with most of that, but my point is that entire economies that we don't understand yet will grow out of blockchains, and not just provide an opportunity to pirate. It's not like BitTorrent (open source, decentralized) replaced Napster, well it did for a few years, but Spotify and Apple Music did because people were fine paying a small fee for music-as-a-service. (If you were in the business of charging fees for music ownership you were largely disrupted, ie record companies).
