You're being slothful again, fakeit. Taussig did not say that the tariffs failed because they were not drastic enough. He did note that the embargo imposed a drastic trade restriction, which we properly call autarky. But nowhere does he fault the tariffs for failing to impose more autarky. That was YOUR comparison made by YOU in YOUR posts HERE. And to that I say that you are in pretty bad shape when your argument has to unfavorably compare the tariffs to the notorious Embargo Act!
Taussig simply notes they were ineffective at accomplishing much of anything they claimed they would do. You, of course, do not like that fact thus you ignore and dismiss evidence of it while attempting to distort what others have said about it into the exact opposite.
Scambling up different thoughts that Taussig had wrt tariffs and embargos does not produce clarity. But that is your specialty. Picking little tidbits and amplifying them is the only way the DSs can argue at all.
His work does not indicate that the tariffs were a miserable failure or that they cannot work nor was he COMPARING them unfavorably to the results of the embargo he was describing the historical context of their implementation. At best he was saying that the infant industry protective intent of the tariffs had been made superfilous by the embargo's forcing of self-reliance. And he explicitly says that infant industry protective tariffs do, in fact, work.
