Hello Gloria:
You ask in reply to my answer to your first question about gold:
“ideal form of money doesn't explain why it worth anything in current time. No one uses gold as real currency anymore.”
An excellent question which goes to the heart of economics, namely the theory of value.
Ask your self why would a woman prefer a diamond engagement ring as opposed to a loaf of bread ? Think about that question for awhile before continuing and see if you can come up with the answer.
The would be bride might say to the man who proposed to her after throwing the loaf of bread in his face that his loaf of bread is worthless. If he tries to explain the value of bread versus a diamond to justify his action she will insist that he is wrong because a diamond ring is worth more than a loaf of bread. Which brings us back to your question about gold why is it "worth anything in current time". Why are diamonds or gold or silver worth more than bread or a glass of water ? You can't eat diamonds or gold but you can eat bread and drink water. So bread has more utility value than gold or diamonds wouldn’t you agree ? So what does determine the price or worth or value of any thing ?
The price of any thing in the market is determined by the consumer. “The consumer confers value by seeking to acquire it. Hence, the value of a thing is never objective, but always subjective… The monetary price of a thing is not the measure of its value, but only an expression of it.”

If you think that because “No one uses gold as real currency anymore.” therefore it should not have any value then perhaps I was not clear in my previous post explaining why gold is the ideal form of money. Gold has value not because it is used as money it is used as money because it has value. While officially gold is not used as money it is money since it can be used as a medium of exchange.
If you want to know why consumers value gold so much more than other more utilitarian commodities then that answer is not a part of economics. Economics is based on human actions which can be observed not on theories of the inner psyche of the consumer.
Your question also leads to another topic called the paradox of value or diamond-water paradox. Why do diamonds cost so much and water which is a necessity of life costs so little ? Or you can say why does gold cost so much and water so little ?
The marginal-utility theory of value resolves this paradox.
“…diamonds are scarce and the demand for them was great, the possession of additional units was a high priority. This meant their marginal utility was high, and consumers were willing to pay a comparatively high price for them. Water is much less valuable only because it is much less scarce, and the buyers of water possess enough to satisfy their most pressing need for it. Additional purchases of water beyond people’s need for it will be of decreasing benefit or utility and will eventually lose all utility beyond the point at which thirst is completely satisfied.”
