The mental shift that most struggle with, is that the NFT ownership is not owning the digital image/file/media/bits (which can be copied on any machine, “Right click save as”). It’s probably closer to purchasing conceptual art (see Sol LeWitt), or similar to owning a certificate of authenticity handed to you by the artist. Or, perhaps somewhat analogous to “owning” digital property such as a domain name.
I agree this tech does not magically make everything more secure. But, for example, you can query the “current owner” of a million dollar CryptoPunk - as long as the blockchain survives, the database record will be secure & immutable, and cannot be changed except from the token holder’s own wallet address.
Reading the Solidity code & querying the contract myself helped me understand the value here is not in the digital media file; it’s in the ledger record (or state).
