It didn’t start with gold standard. It started with the issuance of greenbacks during the Civil War. If they never issued greenbacks during the Civil War, there would not have been an issue with going back on the gold standard.

Sorry. This is quixotic revisionism. What do you think happens during a war? Both the Union and the Confederacy were printing paper money like there is no tomorrow. In the case of the Confederacy, it was literally true.

The previous statements and yours are not in opposition. Both can be true.
