Really now? You might want to do some research on the practical uses for gold.
Thanks for that. I was aware of most of those uses, but some are no longer true, some mainly because of its prestige as a valuable substance (teeth, and jewelry not mentioned), some extremely minor (space suits, a less capable data transmitter than cheaper copper or silver). They are clearly finding it hard to make that list sound up to much.
I was well aware of the main practical uses: jewelry and similar (again mainly due to prestige and value), and electronics.
The value from these uses is insignificant and not why it is the prestige store of value that it is. Without the psychology (belief and prestige), which support each other, it would not be worth very much.
