If the dollar loses status as the world's most reliable currency the United States will lose the right to print money to pay its debt. It will be forced to pay this debt.
It will still print but the value of the Dollar will go down
Dollar is 100% premined, unlimited number of coins, proceeds bomb children overseas, and it funds wars. One guy prints is all, at leasure without restraint, who want to speculate on where this coin is going?
Nowhere!
