> With NFTs the artist needing money can and will mint the exact same JPG undercutting all the fools who bought the previous NFT.

People will still be able to ascribe meaning to which NFT was minted when. So an earlier minted NFT may be more valuable to some than those that were minted later.

Just like when Banksy “destroyed” that piece by shredding it half way, the “destruction” actually worked to increase the value of the piece. In the same way, conceivably, a first batch of NFTs that supposedly should lose value after the artist starts minting a bunch more, could turn out to instead increase in value, because of their history of having been minted and sold before the event of the artist minting a bunch more.
