Thinking this through is exactly what I want the conversation to be about. I'll help you out: [2006] "Counterfeiting of the currency of the United States is widely attempted. According to the United States Department of Treasury, an estimated $70 million in counterfeit bills are in circulation, or approximately 1 note in counterfeits for every 10,000 in genuine currency, with an upper bound of $200 million counterfeit, or 1 counterfeit per 4,000 genuine notes.[1][2] However, these numbers are based on annual seizure rates on counterfeiting, and the actual stock of counterfeit money is uncertain because some counterfeit notes successfully circulate for a few transactions."

I think Bitcoin representing the totality of USD is infeasible, but there may be some adjustments or optimizations to the transaction costs associated with it that make a new currency seem more reasonable (no less scary, certainly, but fright is an emotion and economics is mathematical).
