But its not that simple

What keeps America going is its partners like Japan Europe & Canada keep buying your debt to ensure global stability. We are your cash reserves even if America is broke. i suspect this is done because its allies fear beahemoths like China & Russia taking over. The US does not stand entirely alone as it gets by with a little help from its friends.
Thats what WWII was about. Competing currency blocs seeing which one would take over as the UK pound crumbled after which the US$ emerged the winner.
A collapse of the dollar might lead to a similar conflict if China thinks it can topple the a dominant currency just as Germany thought it could in the 1940s
