Yes, I did mean in the ideal sense, there is a functional purpose for raising the prices of foreign goods IF there is a domestic alternative you wish to boost or expand. But the mechanism for the benefit, IF(big if) there is one, is the increase in price. Tariff (ideally) equals targetted price increases. Saying tariffs might raise prices is like saying stabbing you might wound you. I might have a good reason for wounding you, I might not, but the wounding will happen as a direct consequences of my stabbing you, regardless.
