We need a publicly auditable blockchain. How much gold is in ft Knox ? The public is not allowed to know, the public is not allowed to audit it. For 3000 years we could never audit publicly the base money supply and the movements of the base money. This is the root of our big problems. The govt going beserk with a cartel of money producers because nobody really knows what they are up to.. We have public auditability of money now, for the first time in 3000 years,  and this is the big bitcoin breakthrough. We also need personal anonymity and we have that but that's largely up to the individual. The protocol is fine.
