In the terrifying scenario that the monetary system fails, it’s every man for himself. Food, shelter, security etc is no longer guaranteed…most of us urban dwellers will be like fish out of water…so much that I had not considered…so unprepared for this worst case scenario. 

 but that complete civilization collapse hasn't happened in any other places that had hyperinflation, what will be different this time? 

 It’s the collapse of the world’s reserve currency of the global hegemony…the world is storing its wealth in US capital markets. Its collapse is the collapse of wealth everywhere. It’s a collapse in confidence globally. 

 makes sense
