Yep. Blockchain says I own this case of wine... but the other guy wont give me my wine! Who do I call? The physical, centralized police and the centralized legal system that back it. Without that legal system recognizing and honoring it, it's worthless. And if it all depends on my centralized legal system, then who cares about the decentralized blockchain. Might as well put it in a table in a database instance running on AWS, or in a written contract.
