Indeed they don’t. NFTs are a bit like an immutable record of the intention of the original artist to transfer the copyright of a work, but since this isn’t legally recognized anywhere all it really proves is that someone claiming to be the original artist made a hash of a file and a hyperlink to it and uploaded that to a block chain.

correct. and a copy of a digital item diminshes the value of the original. It is like selling an empty box and then the fool who buys it brags that he bought the most exquisite item that is invisible! Yes, invisible is so rare, like a precious stone, but even more rare. its stupid. But, value is often in the eye of the beholder. Most items both free and of charge are overvalued (again, value is relative). FOSS is usually undervalued (except it can waste/cost precious time).
