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? 
Couldn't agree more that something is either fungible or isn't. You can't have something partially fungible, just a little bit of fun. Could you imagine if the bank rejects a deposit into your own account, yikes, the banks & fiat is looking like a not so fantastic future. I wish it could get better and just incorporate bitcoin & then somehow all of us just don't have to pay taxes. That would be incredible lol
