Privacy is a prerequisite for fungibility which in itself is a defining quality of money over (social) credit.
Society is currently in a state of confusion. People call things money that are far from it. It's based on decades of propaganda.
The only money I currently see is gold, silver, Monero and to a much lesser degree other privacycoins.
Cash is only fungible by decree, easy to counterfeit and not as hard to track as people assume due to serial number readers. Bitcoin, Ethereum, are non-confiscatable NFTs. USDT, USDC, bank accounts, stocks are all confiscatable IOU-NFTs.
People will claim that this does not matter NOW. Maybe they are not transacting enough in scenarios where fungibility is needed the most. Because any centralised entity be it a bank or a CEX will block or confiscate transactions or close accounts. It's daily business that affects 10s of thousands people daily.
