ok. update me in this: you pay for copyright of an art like paint, blockchain store that you are the owner, how you pay, who you pay  to and ... (It has no special advantages ).
 how you are the owner without real content? if you buy NFT, how seller send you the original version? NFT is something like fuzzy ? no real thing but you are the owner?
What is the advantage of the traditional system that you buy the document and receive the goods
