The value of gold lies in the fact that other men may be disposed to work their ass off in order to have some shiny things to gift to women in order to have sex. As you can imagine, the power of gold amongst married couples drastically decreases.
Besides this… History shows humans always gave value to gold. For some reason we got very used into associating gold with value. As such, it is probably something good to have if economy collapses. But it doesn’t really matter if society collapsed.
That is valid for many other resources: iron, silicon, carbon, carrots whatever. Gold has always been attributed some special value, throughout history. That is ok. I don’t think US civilization is going to collapse, why would you think that?
