Next time someone says that to me, I'm going to respond: "Yeah, and what's gold's value based on? Gold's value isn't based on anything either!"
The whole concept of having "value based on" something, is that paper money is paper money and is not worth more than paper.
Both of those statements are false. Gold is valuable because it is rare, prized for it's beauty, it has very useful properties such as its conductivity making it useful in certain (expensive) applications, etc...
Wrong. Example: some natives gave away the gold in return of glass fake jewellery. So gold price is not valued on anything fixed.
I personally don't want to wear gold rings, so I would pay less for a ring of gold than my wife... if I had the choice, which I don't have, when my wife wants that ring, lol .
