if money supply is static all prices must adjust to match the relative proportion of value of trade and scale of preferences of all individuals, this is called price discovery thus, the value of all assets in the world are the amount of monetary units in the world money is half of the equation of all market exchanges, so it is equal to the notional value of all the assets, commodity or equity you can bypass money via barter but in general the equivalence is computed between counterparties in a barter based on the estimate of the monetary value and thus relative prices between them that's why we invented money, to act as a silent, "outside" witness to all trades to enable us to save profits and to use those savings to make opportunities to create more value fiat currency debasement makes it so only those with the money printer have this ability and these are some few thousands of people in the world and they basically are the real ruling class of our modern world
