You were asserting that cash is faster than credit cards. Not true. On the average, in a place like a grocery store, swiping a credit card is the fastest form of payment.
Of course, obviously, cash is more private than traditional forms of non-cash payment, such as credit cards, debit cards, checks, ACHs, etc. The goal should be to develop a form of payment as private as cash yet as convenient as plastic.
But as it is now, you need to avoid the banking system entirely to achieve financial privacy. Taking cash out of an ATM and spending it on whatever may give you some privacy as to the whatever, but the cash is still coming out of your numbered, 1099-issuing, government-accessible bank account.

No. You have never seen people swipe the card multiple times, get refused, only to have to do it again, then ask to do it again because they forgot to ask for cash back? A cash transaction is anonymous, as every transaction should. be. Who the hell should know where and why you spend your money. You made my point—but not entirely.
