No. The US took and maintained it by violence, massacres and war. The status of reserve currency was enforced to the tune of millions killed. It is no coincidence that Bush's invasion of Iraq started on the day that Iraq announced that it will start selling oil in currencies other than the dollar. Clueless people in the US didn't notice that but the rest of the world did. When Albright declared that half a million children in Iraq killed by the sanctions was worth it (https://youtu.be/M8zmnaHpdmY?t=51), "it" refers to the US having about $15 TRILLION dollars for nothing (now drastically decreasing thanks to China) by being the reserve currency.

And your analysis of the impact of having the reserve currency severely under-rates the implications. Just think what would happen if $15 trillion dollars flushes back to the US from the rest of the world. The dollar would holler (to borrow Biden's poetry), hyper-inflation would set in and the US wouldn't be able to import anything because the world would want to get rid of their dollars and not get more. Since the US economy is about 80% services, the implications are catastrophic for the US. On the other hand, the reign of the evil empire would finally end and the rest of the world will be rid of this sadistic oppressor with Mickey mouse propaganda. China will be the new world leader. That is what all the malicious US propaganda against China is all about. ... that is unless the last act of this brutal empire is nuclear war.
