Today when you buy a home you have someone go down to the local courthouse and check that there are no leans against the property and no one else is claiming ownership. In the future, you can imagine a world where that title would live on the blockchain and everyone could see the true owner based on their ability to sign a message with their wallet. You could transfer your title just as easily as any other blockchain transaction. While blockchain titles have obvious advantages, they are hard to pull off because you need 100% participation of everyone in the community for it to work.
The reason we're seeing art NFTs take off first, is that you only need the participation of the creator and a small group of collectors. The creator promises to sign all of their work with their digital wallet and as long as the buyer of the NFT trusts the creator, it works.
