My limited understanding is the blockchain data are distributed enough to get past the "that URL" issue. You'd need to destroy "that unknown collection of URLs"

My limited understanding is the blockchain data are distributed enough to get past the "that URL" issue. You'd need to destroy "that unknown collection of URLs" to eradicate the NFT. The problem as I see it is that NFTs lack any potential energy. Their value is purely kinetic, and expressed in the transaction. If no one wants my NFT, it's so much binary noise.
