If you throw enough spaghetti against the wall, some of it will stick. That doesn't mean you get to eat the spaghetti, nor does it mean the spaghetti on the floor has no cost.
I did not get the analogy. If only some spaghetti sticks to the wall, it means you have a messy wall, less spaghetti left to eat, and spaghetti that isn't all cooked yet. Sorry, but I do not get what you're trying to say.
