I believe you are confusing cash with deposits. Cash (either paper or digital) can be passed untraceably from palm to palm (or palmtop to palmtop, if you will). Deposits, on the other hand, require a method for the bank and the depositor to authenticate each other. In the past, anonymous authentication was rife with problems, but cryptography might solve these problems. However, I think the deeper question is worth considering: what is the justification for anonymous bank accounts? Avoiding taxes just doesn't cut it for me; much as I hate to pay them, I recognise the need to do so.
