I agree. It's not only that it's dangerous (let's say the internet always worked, someone could still ship a bug to the protocol, or too many nodes could fail, or it could get hacked), it's just not even better. Technologists often seem to not start with problems. What is the problem being solved by a blockchain based lock? What pain point exists that would no longer exist? Having to carry keys?

Keys are already decentralized and fully controlled by me. I can copy it and distribute it freely. Putting an intermediary (a blockchain) between myself and access to my house just seems silly.
