It also breaks a lot of the way businesses make and sell stuff today.
For example, several car makers makes cars in Canada, Mexico and the US but sells them across the borders (and globally). Honda makes Civics and CRVs in Canada but sells them in the US, but the Accord is made in the US and sold in Canada. So now if there are tariffs on car imports and especially if there is also a reciprocal tariff, Honda gets hit both ways. What would they do? Make some civics in the US and some in Canada? Seems very inefficient.
