Disagree.
The USD is an international currency and has nothing to do with government. Money is the realm of business, created to facilitate trade.
Companies accept the USD because it is to their benefit internationally. It has the liquidity, depth, and sophistication to operate as a vehicle and invoicing currency.
People mistakenly believe that governments are involved. They like to run their yaps (politicians and bureaucrats) but the money used was always decided by businesses.
As for the Euro, it is a regional currency, not really international.
