It has nothing to do with anything. You are trying to equate conditions under the protectionist policies of Washington DC with the conditions which would have occurred without the protectionist policies of Washington DC.
Either you aren't astute enough to grasp how freeing up trade would have benefited Charleston and others, or you don't want to admit it.
At the same time other Southern ports thrived, which flies in the face of your misdirection.
New Orleans and Mobile were doing well, but they would have thrived to an even greater extent without the protectionist policies of Washington DC hindering their ability to trade with Europe.
“You are trying to equate conditions under the protectionist policies of Washington DC with the conditions which would have occurred without the protectionist policies of Washington DC.”
I’m trying to show that your statement attributing Charleston’s decline as a shipping port was due to the Civil War was false, since that decline had been almost complete by 1840. You’re going to switch positions, and now claim that it was Northern tariffs and economic subjugation, but that’s not what you posted. You wrote that it had more to do with ravages of the Civil War.
