Not end of story.
The reason they believe it's money is that they can see it's money.
On the other hand, with an obscured blochain they can't see f*ck all. (Hence the title "obscured"). So it's even less believable. The words emperor and clothes spring to mind
I can see my balance and I can see my transactions and I know that the ring signitures work, so I don't need anyone (especially a wanabee economist) to tell me that I need to see other people's balances for it to be money. I think you missed the meeting where we discussed that the highest form of human functioning is to think in the abstract, to imagine concepts into being. As long as the cryptography checks out, I'm good. Don't need your seeing is believing concept of money to infringe on my right or anyone else's right to privacy.
