My concern is that you ignore the effects of deflation in your argument altogether, which you simply cannot do.
You are also effectively demoting the US dollar to the current inferior currency of the two to support your little adage, which I find a bit strange.
I believe your intention was just to write a little thought experiment, which is cool. I'm just a little baffled the way some people follow along for the ride without question.
Perhaps obvious, but I hold no cryptocurrency. I'm not saying I never would, but the sheer amount of dreamy speculation like this is exactly what keeps me away from the market.
