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.
The piece of art itself.. well anyone can just right click -> save as. For free.
NFT tech is great for many things. Selling jpegs isn't really one of those things.
You are absolutely right buddy, just yesterday I was on twitter page of a project and someone posted an nft he had minted and the it was an image I could easily save to my folder, and this same thought came to me,
Honestly, I don't think nft is worth throwing money on, better to invest that money on utility coins imo, but what do I know, am not an nft person so perhaps that's the reason I don't see the importance.
agree with you, its right that anyone can copy nft's but you cant do anything with it expect the true owner that he can sell/trade
