No, it doesn't, for if it did, ordinals and rare sats would not exist.
If you want perfectly fungible money, just like you would have in physical cash, look at #Monero.

When someone says something flat on it's face ridiculous, you know that theres no point in continuing the conversation. Just laugh and move on.
I'm gonna have to disagree with you on this one because physical cash is not exactly the most fungible currency there is, since there's so many things that differentiate dollar bills such as serial numbers, signatures, etc.
That's true. The only reason that physical cash is fungible is because it's considered legally fungible. But as you mentioned, because of serial numbers and markings, etc., it's not technically fungible.
