i wonder if gold/silver is used if a natural disaster occurs. do people in syria now or people in christchurch (after the earthquake) use gold/silver or still use fiat? how about greece during the financial crisis? there was a shortage of fiat. you never hear about those things.
Greece never really went through a crisis - it was the media that hyped it into that. The shortage of fiat in greece was only for 14 days. People did not die of hunger in that time, so it wasn't really a problem.
the shortage of fiat was maybe for only 14 days, but during this shortage you did not now that. and if i and many other people would be unable to get our money and did not know for how long, i would start looking for alternatives rather earlier then later.
