This reminded me of another fundamental problem with NFTs, both the owner and anybody else in the world can also download the "art".
This isn't a problem, but a feature. Yes, anyone can download the art, but none of them can provide a proof of ownership of the art except the current owner. Anyone who gives me this article and tells me NFTs are useless is benighted the least.
It's like telling me they own BTC without providing me a valid signature. Okay, you can enjoy looking at the address, but you don't have the rights to move the BTC. When you transact BTC, you do exactly the same thing; you transfer the rights of those BTC. A sign that says it's not yours anymore.
That's not like that at all. Bitcoin doesn't represent something else in real world. Each bitcoin is its own and is a unit of currency. Each NFT token on the other hand represents something else in this case a piece of art, and if that piece is destroyed for example that token becomes meaningless.
It is more like if anyone who wished to could summon an exact version of a painting like Mona Lisa that was drawn by Leonardo da Vinci in their home hanging on the wall that was identical in all aspects each others. The fact that Louvre museum has
a version of it with a certificate doesn't mean much any longer.
For example, the Los Angeles County Register of Deeds could issue NFTs to real estate owners representing ownership of their property.
The question always is not about what you can do but why would you want to do that.
In this case storing such things on a distributed global ledger is meaningless! Storing it in a centralized database in that county or country is already working well enough.
There are taxes associated with transferring property from one person to another, however, the costs I was referring to were things such as performing a title search, and title insurance, both of which are paid to entities other than the government.
This type of cost won't go away. Regular people would have to still rely on other entities to tell them what the hell an NFT is and how to search it in some blockchain and how to transfer the title through it.
Considering that people are reluctant to run their own full node to handle all these acts (which costs a lot too) they will rely on these entities that would ask for a lot more money since this would be a new thing and there would be little competition among those who can handle this kind of stuff.
