Again here you show your ignorance of history. Jewelry was created as a means to CARRY your currency. Jewelry was not created to be "pretty", but to show to others your wealth and to use it in exchange for goods. It was quite common hundreds and thousands of years ago to give someone a ring or necklace for goods or services rendered.

And as for thinking growing food is the path to wealth, historically farmers have been the poorest people in the world. Short term after the SHTF food and water will be king, but those that will be well off years down the road will be those with silver and gold.
