Money with no real privacy is not money, it's a tool of oppression. Any state actor, warlord or a powerful entity can enforce their will if the ledger can be visibly connected to real people. Making you a slave to any system they want to create. A person with no real freedom. Taking into consideration the totalitarian direction world is headed (US, China, etc.), I don't see how having more transparent form of money is a good thing for the ordinary people.
