Bryce, we'll make you a believer in online clearing yet!

This is essentially the point several of us have been making, that if
"anonymous bank accounts" are allowed (_technically_, no problem), then Bob
can take his "possibly watched" piece of cash, deposit it with his bank in
his anonymous account, withdraw the same amount (or more, or less, it
doesn't matter if the account is truly anonymous) and neither Alice nor the
Bank know who got it.

As you note, Bob can even open a new account, deposit, withdraw, close the
account. This makes the bank a "digital coin laundry," such as Lucky Greene
and others have talked about.

If forbidden by law in the U.S., no problem using offshore banks.
