It makes no sense because you don't have the facts.The US currency conspiracy theory still makes no sense to me.
America wants countries to use US Dollars for oil so bad that it ....that it banned Iran from using USD to sell oil

Iran was not selling oil in US Dollars, it was selling it in all sorts of other currencies, but basically any currency besides it. The US didn't ban it from using the Dollar, the Iranians themselves did it.
Iran stops selling oil in U.S. dollars
The Venezuelans were never using Dollars to sell oil, they were selling in Euros mostly. Nobody banned them from the outside to possess Dollars, they banned them themselves.
Dollars Are Out, Euros Are In as U.S. Sanctions Sting Venezuela
FYI, every country with a fiat currency turned reserve does this, the US is not the only one. Its the only way to make monopoly money valuable when its not backed by a precious metal or other rare resource. The US does it better because we also base the value of other currencies on the US Dollar, so if the Dollar collapses, it also devalues other currencies too (which makes them desire to help keep the US Dollar strong).
