Ginsburg's dissent-by-way-of-concurrence is a beautiful thing
In agreeing with Justice Roberts on the outcome, she also demolishes his reasoning and the reasoning of the other conservative justices. Especially regarding the stupid "can the government force you to eat broccoli" argument.
Consider the chain of inferences the Court would have to accept to conclude that a vegetable-purchase mandate was likely to have a substantial effect on the health-care costs borne by lithe Americans. The Court would have to believe that individuals forced to buy vegetables would then eat them (instead of throwing or giving them away), would prepare the vegetables in a healthy way (steamed or raw, not deep-fried), would cut back on unhealthy foods, and would not allow other factors (such as lack of exercise or little sleep) to trump the improved diet. Such “pil[ing of] inference upon inference” is just what the Court refused to do in Lopez and Morrison.
Other provisions of the Constitution also check congressional overreaching. A mandate to purchase a particu- lar product would be unconstitutional if, for example, the edict impermissibly abridged the freedom of speech, interfered with the free exercise of religion, or infringed on a liberty interest protected by the Due Process Clause.
Supplementing these legal restraints is a formidable check on congressional power: the democratic process. As the controversy surrounding the passage of the Affordable Care Act attests, purchase mandates are likely to engender political resistance. This prospect is borne out by the behavior of state legislators. Despite their possession of unquestioned authority to impose mandates, state governments have rarely done so.
When contemplated in its extreme, almost any power looks dangerous. The commerce power, hypothetically, would enable Congress to prohibit the purchase and home production of all meat, fish, and dairy goods, effectively compelling Americans to eat only vegetables. Yet no one would offer the “hypothetical and unreal possibilit[y],” of a vegetarian state as a credible reason to deny Congress the authority ever to ban the possession and sale of goods. The Chief Justice accepts just such specious logic when he cites the broccoli horrible as a reason to deny Congress the power to pass the individual mandate.
