Now that we are transitioning to B2C and P2P (C2C) globalized commerce, we need in some areas (especially intangible Internet commerce) a globalized unit-of-account and exchange.
It doesn't matter what the "unit-of-account and exchange" is, or whether it's globalized or not.
The trade value of a collateralising asset is independent of how it is measured.
Prior to 2009 there were no electronically manifested collateralising assets. That is because such an asset needs to be capable of reconciling two key properties in a single trade:
ownership
possession
Subsequent to 2009, this was possible and the value will accrue accordingly.
The currency units that are used to measure that value are irrelevant.
