I think there is a missing link in the middle of this question, paper currency-accounting currency-Bitcoin (digital currency).

The emergence of bookkeeping currency in history is the re-establishment of the trust system. No matter what means the world economic entities use, they are actively acting as the voice of bookkeeping currency, especially the right to bookkeeping of world currencies, the Bretton Woods system, SWIFT settlement system and so on.

Although Bitcoin does not have legal and political attributes, it has completed the establishment of a trust system through code and smart contracts, and achieved the balance of economic interests through non-human factors.

Under the criticism that banknotes can be issued indefinitely, it is impossible for the economic crisis not to occur. The root of everything is that the dollar-centric world currency uses unequal means to plunder the resources of other countries.

The history of paper money actually gives us that the essence of currency is the carrier of value exchange, and unreasonable monetary rules will always be eliminated by history. Although Bitcoin now appears to be a utopian currency, in the future, international currency is not centralized, let alone a sovereign country. Bitcoin will become a good medicine for countries around the world to get rid of economic crises.
