Not at all, but then you didn't accurately describe how it worked. The Foreign ships didn't bother going to Southern ports because there was no advantage to doing so. Coastal packet shipping companies, (owned by pretty much the same people that owned the larger international shipping companies) moved cargo from New York to other ports.

The navigation act of 1817 made it unprofitable for foreign ships to go to Southern ports. That's why getting out of the deal would have been such an economic boon to the Southern port cities. It would have also reduced shipping prices between ports because north eastern owned shipping companies could no longer gouge because they had a monopoly.

Then who took the cotton from Southern ports to Europe? U.S. ships?
