Gold is actually really good at transferring and measuring value. Think about what a "good" measure of value would be have. It needs to last over time, not corrode or dissolve to the forces. It needs to be distributable, Divisible.. to be ubiquitous. Hard to create/refine, hard to find, so supply can't easily be inflated.
It doesn't matter what the object that is being used for exchange of value or holding value, that's why you can trade and barter random objects. But if you condensate down the properties that make a GOOD money, then gold is more than just a shiny metal.
"The amount of value in the world is increasing so you want to exchange medium to grow with it.." we find more gold every day, so there is an easing already happening naturally. And even if there wasn't, imagine having an exchange currency that literally never inflated... that's GOOD. We have been hoodwinked into thinking that we need inflation to keep up with goods and services, literal stockholm syndrome taught by the FED.
