oh so when you spend to someone they can't investigate the history of the funds? and the VAST majority of people dont tie their identity to their Bitcoin? and then transfer it on a public ledger? I'm really excited for a Bitcoin standard when ALL my counterparties can do adaptive pricing based on what chain analysis tells them about my wealth.

You're conflating anonymity and privacy. You never have any privacy on bitcoin L1, but you can have weak pseudonymity that sooner or later is gonna bite you in the ass once you inevitably fail at utxo management (and if you're one of the few who can do it, congratulations, so am I, but having to do this is a downstream consequence of a badly designed system). So that's what he meant, a bank's ledger at least is not public (it would be terrible even if the KYC data of the customers was elided, it's still information that shouldn't be public). Bitcoin's? Public. Forever. You never making any mistake ever versus Relentless public eternity. Guess who'll win, 99% of the times, for 99% of people?
