I thought your original comment was misguided. I think there are cool and interesting things happening with blockchain technology that are related to ownership, and that are based on locks. But the fact that some new technology touches both doesn't mean that traditional locks do.

"Ownership" is a legal concept. A lock doesn't prove ownership in any way. The person with the keys to a car or a house isn't the owner of it. The person listed on the pink slip/deed is.

I started out saying that locks are just about access control, then remembered the old "locks keep honest people out" adage, and added "intrusion detection" to the list.
