Are all food items necessities? I don't know, maybe? Are ice cream, trans fats, soda, candy, filet mignon, alcohol, etc. not luxuries?

I empathize with the position that any tax on a food item will disproportionally impact the poor. And I agree, everyone should have a baseline level of housing and food accessible to them regardless of their circumstances. But if a food item has huge negative externalities, surely we should do something to limit its appeal and consumption, right?
