That is just a fundamental misunderstanding of how Plastic works. His powers go well beyond "molding what he has into looking like something else". He can fully transform his body into working machinery, producing light from lights, or smoke from engines, or functional rockets and cannons. In the Terrifics he forms working guns and gasmasks. He is an outright cartoon character that obeys no laws of physics, not just a guy who can stretch into funny shapes.
