If by "dollar standard" you mean living and holding them, I don't think that's the case. Super rich thrive with usd inflation, as that's how that are able (through boom and busts) to extract the wealth from the have-nots. In other words, inflation is great, cantillon is even better.

Central bank interventions show growing state of instability in the fiat system

I think no-one has factored in some kind of default or financial reset where the fed does not stimulate or inject or bail out. 

This will probably not happen in our life time, but most super rich etc. are on the dollar standard and its not in their interest to have it inflate too fast? 

So there is a chance that they will let the economy deflate imo.
