Dude I can literally point to any UTXO and tell you every single address that has held it all the way hack to a coin base transaction.
You can cite Aristotle as if that hand waves away the abject silliness of what you're saying. "Fungible" is a word that means something, whatever you're trying to extrude it into is not it.
"Fungible" means, if you put two of something on the table and tell me I can have one, I wouldnt give a shit one way or another which one I take. That's it.
