We know it is not constitutional. Fedgov has no police authority within the States in the area of health. On the flip side, we have 9th amendment rights. Whether the Courts agree is irrelevant.

Corporations which have accepted any kind of federal funding or loans or credit are further obligated to apply the Constitution.
