I do not think that I would add up much to the precious conversation about the importance of gold in good and bad times. However, I strongly believe that the power of questions raises awareness which is always needed.  

Why humans throughout history never swayed from gold?  

Why do all the central banks hoard and preserve gold?  

Why do all investors diversify their investments and buy gold?  

The answer that does not need a PhD in economics and an army of talking heads on CNBC and Bloomberg is that central banks cannot print it whenever they want. Period.
