Sure, inventory is waste. You need to store it, protect it and organize it. Maybe you never even end up using all of it.
The thing is that without inventory, you can't build anything. Manufacturers optimize their supply chains to keep minimal inventory and reliably acquire the supplies they need just before they run out.
...but the creative supply chain is not reliable. You need a lot of inventory because good ideas might not arrive right before you need them. Fortunately, a binder full of notes is a lot easier to manage than manufactured parts for thousands of cars.
