The whole cryptocurrency part is just misdirection and a red herring so they can claim that it is "decentralized". This is a banking consortium and they want to leverage the FB network effect to rent seek on cross border payments and the unbanked. The problem with your analogy is that unlike your CeC tokens, the FB Mafia completely controls whether you can give them to someone else or not. You can't trade them on their (fake) blockchain to someone else if they say no and without making a direct payment to the FB Mafia. It is also likely you can't even try to do the exchange without using the FB Mafia's wallet application. There is no physical thing that can be exchanged like with your tokens. They have also said they will comply with any government regulations. So if someone reports your CeC tokens as stolen, the FB Mafia can just steal them back and you have no recourse.
