This would transform the dependency graph from a DAG to one with cycles and thus the recipe could not be resolved
A Kit-Kat bar consists of some external components, like wafers and chocolate. It's only the combination that turns them into a bar.
So you can bootstrap production by grinding the components and mixing them: it produces a Kit-Kat bar in a ground state. After that, you can produce more and more nominal-state bars.
But nobody can build them from scratch. If at any time they are all eaten, that's it!
Perhaps you are confusing the (discarded, and rightly so!) Unified Linear Field Theory with the (universally accepted, as it should be!) Unified & Closed Modular Field Theory?
Time ultimately, like all dimensions, is a meaningless loop. Of Kit-Kat’s.
Leaving only one last physics question to settle definitively, by prose, coercion, poison, blade, and projectile: Do the Kit-Kats form a Dünkin torus or a Möbius strip?
Entire schools of sugary confectionary thought hang in the balance!
