Like I said, the only thing that matters is value. Liquidity is guaranteed and equal for all currencies everywhere around the globe. I can go on any market and exchange my rubles for whatever. You are correct about it being worthless, but I can still literally go down the street here and buy / sell rubles all I want, as can anyone on the planet. US dollars doesn't provide any greater access to goods than any other currency. The funny thing about fiat is that we all think we actually have currency and that it's controlled by reserve banks. The reality is that none of this money exists, it's all electronic and we are just moving numbers around between ledgers. In reality, what we actually have is a global metacurrency that is the exchange rate and we actually trade the exchange rates by proxy of local currencies. What denomination of local currencies allow is for sovereign nations to maintain sovereignty and not be under the thumb of another sovereign nation, which is basically guaranteed by their militaries. Which, as mentioned earlier on this page, is the real guarantor of value for the usd and has nothing to do with american dollars giving anyone access to more of anything. That was my point.
