I appreciate the analysis, but that's not the message I took from the post. By making property that is unique to one person, that property cannot be sold, and is, in a sense, valueless. You're probably right, though, that the main use case for this will end up being companies selling access to ultra-exclusive events with "bragging rights" NFTs associated with them. However, the technology could also enable something much more humble, like a shell from a beach taken as a souvenir from a holiday, or something as personal as just a memory.
