This is all just because we are afraid of the T word. A uniform tariff and matching currency export control achieves the same effect, and doesn't impose US hegemony on the rest of the wrold.

And, seemingly, a tax authority (the IRS) would be better equipped to calculate these amounts anyway.
Nope. A blanket tariff that applies to everything equally.
