Many of last year's NFT collections are for social clubs, where proving current possession grants you access.
(if you made it this far in this thread, I should reiterate that NFTs and NFT collections have many differences. A lot of people that spend more energy not using NFT's have not noticed)
These social clubs can have a physical real world component such as conferences and events. Some fast executing NFT project creators have been able to pull the logistics off quickly, thinking of Bored Ape Yacht Club (now with a large $450m investment led by Andreesen Horowitz' a16z), and Veefriends
Many more of these social clubs are online only, including access to online worlds that are currently being called Metaverses (or usually "the metaverse", pretending others do not exist), many are for benefits conveyed in games.
But even more commonly, the interoperability is leveraged and third parties offer access to their own assets and NFT collections by granting access to people that currently possess another NFT collection. Some of these things can be very valuable. Other times, these are "airdropped" directly to the holder of a valuable NFT.
As this is programmatic, It is impossible for any of these things to ever factor in a duplicate, or for the duplicate to accrue the same value and demand (unless someone successfully built a community around the duplicate themselves)
I apologize for my terseness. The private cryptographic key, which is only known to the owner, can be used to sign transactions and such, but it is never directly shared out. Thus, cryptography prevents the retrieval of the key from the outputs.
