That's literally what fungibility means
Yep, that was my point.You could argue it's not possible to "improve fungibility" because it's perfect already.
I don't think there's a reason to put this verb next to it. Something is either fungible or it isn't. You can't have it both ways.It's like complaining to a bank that the banknotes you received were previously used in a crime. It doesn't matter.
Even worse. The bank rejects your deposit and requires personal info to... Verify you're an idiot?
