People complain paper money is worthless we just think it is valuable so we should switch back to gold.

But the thing is gold pretty much is as well. There is a belief it was historically valuable because it was rare, but that's not the reason why. Historically it was considered valuable because people believed it being the only known noble element at the time and resistent to oxidation and chemical reactions, that it was immortal and held the key to immortality. It was valuable based on a magical thinking and we just keep going along with it in modern times because of tradition. There's some modern alue in it being used in electronics and rare, but not at the clip that gets valued at and there are rarer and more useful elements out there. Also it's usefulness in relation to it's availability isn't at the same ratio as more common minerals and elements.

Long story short the value of gold is just because we believe it is the same as any other currency. All currency is pretty much worthless bullshit unless we believe it to be otherwise.
