Interestingly, NFTs could solve a lot of issues with deeds. This was posted on reddit some years ago
Spent some time working in real estate fraud. Your question [regarding somebody hacking your wallet and stealing the deed] creates a scary scenario but let me assure it isn't better now. You would be surprised at how hilariously easy it is to get on title for a property and start fucking with it.
All I need is the current owners information (public record) and I can go record a deed right now. Its called a wild deed and while they don't usually cause any trouble if your state laws are decent you can very easily wake up to someone else's name on your title and an annoying legal process to clear it.
It happens by accident ALL the time and people usually don't realize it until they try to refinance.
AINs that are different by a single digit are more than common. Deeds can be hand-written and there is a lot of room for human error in the recording process.

Now your neighbor "owns" your property, your lender is sending you angry letters, and you have a court date just to delete a document with a typo on it.
This is before we get into criminals actually trying to steal from you. The damage can be catastrophic. You will lose your home if you sign the wrong paper or (more recently) put your thumb on the wrong ipad.
There are issues here for sure but don't think a paper deed in a lockbox is much safer than an nft. It's just how we've always done it.
While I think the collectable NFT craze has crashed and burned, it was an interesting experiment. I think NFTs in some way have a use case. While not specifically an NFT, Buenos Aires for example rolled out crypto/blockchain backed Identification.
