I heard people want to put things like deeds on the blockchain but what happens if someone steals your keys? Do they own your home? Of course not. A system should have trusted intermediaries and centralized sources of record. If someone hacks my municipality and updates the record that says that they own my home, obviously that wouldn't hold up and that should be reversed. Why would I sacrifice that safeguard for technical elegance or promised efficiency? Why do I want to allow permissionless transfer of my deed to any party? What problem are we trying to solve here?
