NFTs, in addition to being collectibles, can be used to unlock access to features, like an exclusive chat room or give the holder access to bonus content only available to those X number of NFTs which were minted. Furthermore, secondary markets could easily exist for transferring access, something that is not really doable these days with accounts.

I’m with you that the current art/collectible NFT craze seems a bit much, but I actually think the future utility of this “access” property is where things will get interesting.
