For NFTs it’s very easy to grasp their novel use case. Any digital asset (content subscriptions, software licences, passes to gated communities, in-game items etc. — all are supported by real, functional examples today) can be distributed easily to the wallet of your users and you don’t need to worry about building additional middleman infrastructure to store and verify the data or to enable your users to trade the assets. In fact the users gain unprecedented property rights: they can sell the assets freely, take a peer-to-peer currency loan against them, exchange them for something else, destroy them etc. As the creator of the NFT collection you don’t need to worry about how that happens because it takes place on decentralised protocols that are already operational.
