As a point of fact, it isn't true that the dominant currency imposing costs is new...that has always happened. Britain did it in order to secure continued use of the £, and the US has done it before now. It is a normal extension of foreign policy (because finance is not separate from politics, as the Rusal example shows).
It isn't some kind of authoritarian aberration either. The point is that the US has most to lose from a system of free trade so is the one who shoulders most of the burden for securing it. You don't secure something by sitting back and letting people ride all over it.
And yes, some people who don't want to play by those rules will grouse. But the system will always lean towards one dominant currency, it is just easier that way (the UK losing control was was unexpected and took nearly six decades to play out after the point of obvious decline). The world is awash in dollars, no need to worry (if anything, the issue is that some are too reliant on too much dollar funding...not that the world is moving away).
It is kind of unfortunate that the Economist keeps getting worse. The election of Mango Man and Brexit has truly addled the minds of some generally smart people (or made clear that their smartness wasn't actual intelligence but an ability to just parrot whatever they were told was "right").
