Yes, even I'm sympathetic to the anti-regulatory uses of cryptocurrency(donating to Wikileaks or safely buying drugs), but I haven't really seen a use case for blockchains or cryptocurrencies outside of these. From what I can see, blockchains can only be used to keep track of digital or network resources, that can be transferred and validated on the network itself. So you can track stuff like Zorgbucks or DNS addresses on the ledger, but you run into serious problems when you need to keep track of meatspace resources. The local governing authorities don't give a shit about who your blockchain says owns this toothbrush or this plot of land. The only way to track and enforce transfer of this kind of stuff is if you create a fleet of Robocops to go along with your blockchain.
