"Shares are not fungible, these are not NFTs. " This sentence is contradictory. Shares are either fungible (they are), or they're not, in which case they are 'non-fungible', like "non-fungible tokens." In this case they are, because one share is like another. If you and I both have boeing shares, we can trade one for the other, and still feel like we got a fair trade. Additionally Boeing has the ability to mint new shares. And if they do that, they mint shares like yours and mine.
