Option C: Don't bring in this spell in the first place.

A: Paper in a paper mill becomes paper in a wide, long sheet before it is cut into enormous rolls. One sheet of paper, RAW, could therefore be Rebuilt to become several tons of it, no problem, as that sheet was was an integral part of an enormous roll at one point.
B: Following this logic: I have a gold ring. It breaks into several pieces and I can only recover one. Since gold is a raw material, it cannot be Rebuilt?
C: Yeah, laying down a flat fiat of "Because I say so!" never occurred to me.
