"the value of Gold is based on the will of the people"
I think that is true to the extent that "the will of the people" is expressed by their actions in wilfully buying and selling gold. It just so happens the people have been willing the price down in the US dollars for the last four years and that anyone who has bought gold since 2010 has paid to much for it.
Afterthought: Wow. I thought "The Will of the People" is an abstract concept that died during the French Revolution.
