It's which came first the chicken or egg?
The fall of the dollar will happen because anyone(everyone) with significant wealth will divest from the dollar CAUSING the de-dollarization. That's the point of the indicators.
So, whoever has significant wealth will do exactly this and take out loans to purchase productive assets and then, later on, pay back much less because the dollar lost value in the mean time.
This works out as long as the interest rate is lower then the actual annual loss in purchasing power.
