Very much this. It is disappointing and scary to see tech people, of all groups, who like this idea.
Cash is a perfect currency. It is strictly peer to peer, fully fungible, can't be blocked or censored by any party, anonymous, has no dependency on anything (still works when the electricity and internet are down).
Cash is kind of fungible, but not really. Every bill has a serial number, so every bill is unique. This is what it means when money is "marked" in a police investigation, they give bills with known serial numbers to bad actors in a criminal enterprise and then recover the bills at the other end of the enterprise proving the connection.
In common practice it's fungible in the sense that one twenty dollar bill is as good as another. In edge cases though it's not quite fully fungible.

This has nothing to do with fungibility unless a bill’s serial number affects either your ownership of the bill or whether the bill will be accepted as payment.
Fungibility is related to being indistinguishable for the purpose of economic transactions, not being physically indistinguishable.
