I believe something like this happens in pharmaceuticals where creating or recertifying manufacturing capability is incredibly expensive. If a drug price drops below the point where there is insufficient margin to create or sustain manufacturing capability, it stops getting made. This is one source of drug shortages and, to my understanding, why the world health org created a list if essential medicines. This would be a list that countries could use to develop availability controls.
