But you'd park your capital in places that are safe havens and convert out as late as possible to the (increasingly worthless) dollars. Arguably we're already at a place where keeping any non-emergency funds in USD is a terrible idea.
My point is exactly what you said: that you'd see a flight of capital to hard assets like gold and bitcoin to shield it from inflationary forces and their contagion. In that scenario, bitcoin is no more a "ponzi" than gold.
