 The states, if they had conflict over things like tariffs, could then go to the federal government and get some sort of remedial measure to remedy the conflict. It wasn't supposed to be that the feds could regulate anything that went over state borders, right? That's absurd. It's absolutely ridiculous. And it blows the lid off of all the enumerated specific powers that are granted over certain things, and it destroys the concept of the 9th and 10th Amendments.
