So it's amazing at miseducating and misinforming politicians in impoverished countries?

In industrial economies money is credit and countries issue their own money by setting up a banking system to lend it into existence on security of domestic tangible capital to promote wealth formation and create liquidity for domestic employers to make payroll. Since the early 1700s western governments have known how to create stable money from nothing without any gold, private banks, or external investors by lending it into existence through land loan office system.

It looks like El Salvador didn't create its own money before and was just using US Dollars sent back by emigrants though.
