It's laughable that tarriffs and import taxes only apply to physical goods. If the EU had even an ounce of self-respect, the second the US came out with the tarriffs, they would've come out and said:
"We think this is a fantastic idea by Mr. Trump. Aligned with his views, we are instituting accompanying digital tarriffs to fix the digital trade defecit. We're sure he'll agree that the trade balance should be corrected in both the physical as well as digital worlds".
And that's why the US is so mad at the likes of Brazil - finally, after decades of getting rinsed, countries are starting to take (wholly insufficient) measures here and rightly instituting the equivalent of digital tarriffs.
