It is simply false to claim that the beginnings of an industry means that the country had "industrialized" clearly the very beginnings of something is not the entire thing. Taussig clearly states that there was a great expansion in cotton mills in the quote I referenced.
And "...would hardly have been much retarded" does NOT mean "did not work."
The plainest English Taussig uses only says the tariff may not have helped much but he is extremely circumspect in that "conclusion."
Looks plain enough to me:"little, if any thing, was gained by the protection which the United States maintained in the first part of this [the nineteenth] century."
You simply don't like that conclusion so you try to obfuscate it with quote mining and out of context qualifiers.
