Gold has an incredible use that is unmatched by any other substance or currency discovered or invented. It’s a superior form of money. It is superior not because of tradition or superstition, but because of the physical qualities it possesses in various measures that no other substance possesses.

In the same way that aluminum has inherent, immutable qualities that make it particularly suited to build airplanes out of, gold has inherent, immutable qualities that make it a superior form of monetary asset.

Those qualities in aluminum are a high strength to weight ratio, relative abundance so it’s not too expensive, rigidity, plasticity, durability, etc.

In gold, those qualities are durability, portability, divisibility, fungibility, recognizability and perhaps most important these days: it is not actively being devalued as a matter of stated policy by the world’s financial superpowers like every major currency.
