Those who swap paper for Gold, do so because they believe that the value of the dollar is going down.
They talk in terms of Gold going up, but they instinctively know what it is that is really being measured; they just don’t ‘get it’ intellectually.
Nobody ever talks about Gold going to zero value.
Gold will keep on doing what it has been doing in the marketplace for 3,500 years; being a store of stable value. That is why it is in a constant process of being used to measure marketplace value – including central bank debt notes.
