No. Someone is traveling to Europe, going to a restaurant and paying for the Euro nominated beer with his US based VISA and starting to claim that hey, cool, I paid for the beer with USD. You see, I lost a portion of my USD balance and gained a beer.

If you insist that the guy paid his beer with USD, it is going to be very difficult to discuss about anything as the meanings of the concepts are so twisted.

It is quite obvious that using a credit card that then accepts BTCfrom you does not mean that you use BTC to pay for anything but your credit card bill.
