> In the US your public bank account number is effectively a password to debit your account! There’s literally no authorisation at all! Don't you also need the routing number? How does this differ in other countries or anywhere that checks are used?
Yes the public account number and routing number. Which are printed on my card, statements, might be read out loud, etc. My bank in the UK would not let you debit my account with just the numbers. I’d need to authorise it. How do you stop people debiting your account with whatever they want?
Being able to undo mistakes means far more than anything else; it means it's permanently superior to all ""web3"" tech no matter how much fancier they may make that look.
