In theory, possibly? But for things like vehicles, and especially land, the existing processes work OK in the places where they are well developed, and where land registries are unclear, NFTs probably don’t help much because the bigger problems are things establishing who exactly is the owner and do you have an effective court system with fair rule of law. An NFT would also have to accurately describe the asset which gets trick with land since it tends to slowly move in places and at the same time old records remain important. Eg in the UK compulsory land registration has been rolling out since the 1920s and the register has existed for nearly 160 years, but title to something like 10% of the UK is not in the land register, and may never be.
