It's also not rational to believe that a sovereign currency which is backed only by government fiat cannot crash due to inflationary spirals. After all, if it should happen to be the case for the currencies we all use right now, it would be the first time that this experiment, which has been tried often enough throughout history, hasn't ended in that particular way. We've put all our eggs in that basket, and it's working... so far! I'm glad there's a hedge against that outcome though. If the worst happened, and the debt balloon triggers ECB, the Fed, and their Asian cousins, to initiate hyperinflationary money printing, we'll all be grateful that there's an alternative to going back to shipping convoys protecting boats loaded up with gold and silver. I don't even think the aforementioned hyperinflationary spiral is inevitable, or even more likely than not. But I repeat, it is irrational not to consider it a real risk, given history, and that outcome would lead to immeasurable human suffering, which cryptocurrencies cannot prevent, but can at least ameliorate.
