In what way is money not a resource at all levels? There's a finite supply of money that can be added to, taken away, allocated, or fluctuate in its price according to any other arbitrary unit (i.e. dollars in terms of euros, or in terms of baseball cards, or pounds of steel). Just like legal entities or "social liquidity", the supply and allocation of money is an ultimately imaginary thing that nonetheless exerts real world influence on how many other resources and products are created.
