Please provide a source for that quote.
Also, you may be aware that as of 1854 with the introduction of the warehousing act, goods were received by a buyer in a federal warehouse with tariffs being charged on the actual purchase price. Those later transshipped to Southern ports were charged a tariff at that location. In your table you list the tariff rates as:
1800 _____9.1 percent
1825 _____20.1 "
1850 _____39.7 "
According to the BroJoe's tables he presented, the rates were:
1800 _____10.7
1825 _____22.3
1850 _____22.9
I am unsure as to what leads you to using words such as "minimal" or "libertarian" since those are political, not economic terms, and in no way is mathematically defined.
If you are inclined to make comments on Souther reaction, then include data for the Morrill Tariff, which was the issue, and not data from 30 years before.
Keeping in mind that increases of percentages in the range of 3-4% were inflationary, reduced the market for Southern goods not only in Europe but also Central and South America, and resulted in devaluation of the next year's production when tariffs increased.
But,the point is that you are changing the premise of the discussion to cover Brojoe's mistaken post. Whatever.
Of course the Morril tariff was not the issue, it not being passed at the time that the southern states pretended to secession.
If they had merely voted against it, it would have not passed.
Of course that would have required courage, virtue, loyalty to their oaths, and was accordingly beyond them.
The word “minimal” refers to the taxes gathered as a ratio of the GDP.
When the tax rate overall is less than 2% that seems pretty honestly described as minimal. The radical growth in GDP seems to indicate the phenomenal success of the “American System”.
