And I reject the notion that case law is superior to Constitutional law. In fact case law is doomed to failure more oft than Constitutional law because it depends on rulings which cannot themselves be guaranteed correct.
The two are now mutually exclusive as the case law now has the exact opposite of what the Constitution says as "constitutional."
The commerce clause is embedded in "with Indian tribes" and "with foreign nations", to hold that intrastate commerce is sufficient impactful of interstate commerce to allow its regulation is to say that a foreign country's internal commerce may likewise be regulated by Congress. This is absurd on its face, and would rightly be considered an act of war by that foreign state.
