While generated robot videos offer a scalable alternative, existing methods treat them as real robot data by recovering pseudo-actions from synthesized pixels. We argue that deriving low-level control from generated visuals is a mismatched abstraction. A video captures only \\emph{geometry}: the spatial trajectory representing the \\emph{where} of a task. A real demonstration captures \\emph{control}: the exact motor commands representing the \\emph{how}.
