Endlessly frustrating trying to explain why gold is a sketchy "store of value", one that is almost entirely dependent on human belief to maintain its supposed worth. You can go through the history of gold in feudal times and its increasingly kludgy function as a medium of exchange as market economies emerged, about how and why promissory notes and paper currencies took the place of metal coins, the belief in gold's value stubbornly persists.

Right now BTC teeters on that same precipice of kludgy functionality. The strict limits on its supply guarantee that if it retains value in the eyes of its holders then it will be a deflationary store and will not be used for its supposed function as a currency. I think that most people have difficulty with issues of scale, that the difference between a million, a billion, and a trillion is not intuitive to them and in like fashion the scale of a global economy sufficient to provide the basics of life to six billion humans is hard to visualize. So tempting to seize on simple looking answers, like blockchain "currencies", for incredibly complex processes;)
