That's the neat part.
What you are buying is "digital ownership". Not the item itself. You are the owner of a piece of data that says you are the owner of a piece of art.
Agreed, NFT will be tokenized into the token with unique hash to be used as proof of ownership but when it comes to the real ownership in front of regulation and this is not strong enough. I wanna say that someone else can add this NFT and then it was generating new unique code for the NFT that already copy pasted again.
The piece of art itself.. well anyone can just right click -> save as. For free.
I see that some people were using this to copy pasting NFT and then add it into the another platform.
NFT tech is great for many things. Selling jpegs isn't really one of those things.
TBH artwork was not fully worked with NFT. it's quite difficult to know which was the real ownership.
