True. But your editorial was talking about goods entering at New Orleans and spreading througout the country, supposedly without tariffs being paid. My point is that goods going up the Mississippi would have entered the U.S. at one point, the Tennessee border. It would not have been hard for the U.S. to apply their tariffs there, or at whatever U.S. city they were landed at.
You keep trying to put forth that argument , and I keep pointing out we can't even control the Southern border we have now. Massive amounts of illegal goods flow across it, and we have better means of controlling it now than they would have then.
