I don't understand the willingness of the masses to willingly give governments complete access to all of their transaction data. At least in the U.S. bank transactions are feebly masked by institutions. I have no doubt the government gets bank transaction data, but with Pix, it's just making it even easier to monitor what you're doing. Is it that the transparency makes it feel good? No middleman selling it or giving the facade of private transactions?
I do not see how this is better than cryptocurrency, which, while not fully anonymous aside from Monero, is at least decentralized.
