I agree with you but in the world of widespread terrorism, tax evasion, money laundering, fraud, crime and rogue states and regimes, dictators etc. banking secrecy does not exist. With some kind of open and transparent banking network banks could vote to allow or disallow transactions respecting privacy just like Bitcoin does with pseudonymity and also "catch" bad guys who do aforementioned stuff. SWIFT prevailed because it standardized banking payment orders but no regulator really and fully knows what happens and flows inside SWIFT network. DeFi(Decentrilized finance) could be better than traditional finance if it implies transparency which is safe and useful at the same time.
