"Gold gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility. Anyone watching from Mars would be scratching their head."
Buffett is the biggest beneficiary of the current system. Would you expect him to say anything else?
"Warren Buffet is observing the painfully obvious - gold is a wasting, non productive asset. Its only value is to be a store of value."
Gold was also used as exchange medium for thousands of years. Gold has important industrial uses as well.
Even if you accept that gold is a "wasting, non productive asset" - ( which I don't ) - is there anybody here that believes that the current system is cheaper to run? After you dig out, refine the gold and produce the coins - the maintenance of exchange system based on gold must be an orders of magnitude cheaper than the current system and MUCH more difficult to be gamed by insiders. It's mind blowing that a gold coin from the Roman times still has the same purchasing power today.
Of course silver and copper can also be used as store of value and exchange medium. Gold just happens to be more rare and this is the reason it packs more value per certain weight.
In conclusion - Here is a quote from ( Great Irony! ) Alan Greenspan:
"In the absence of the gold standard, there is no way to protect savings from confiscation through inflation. There is no safe store of value. If there were, the government would have to make its holding illegal, as was done in the case of gold. If everyone decided, for example, to convert all his bank deposits to silver or copper or any other good, and thereafter declined to accept checks as payment for goods, bank deposits would lose their purchasing power and government-created bank credit would be worthless as a claim on goods. The financial policy of the welfare state requires that there be no way for the owners of wealth to protect themselves. This is the shabby secret of the welfare statists' tirades against gold. Deficit spending is simply a scheme for the confiscation of wealth. Gold stands in the way of this insidious process. It stands as a protector of property rights. If one grasps this, one has no difficulty in understanding the statists' antagonism toward the gold standard."
