Because that means we in the US may as well quasi-nationalize major European investments in the US like VW, Siemens, Saint-Gobains, OnSemi, NXP, Arm, and Nexperia and target European luxury cultural exports like Cognac (LVHM), Wine (LVMH), designer clothes (LVMH), designer purses (LVMH), and others like China did.
As a result, oligarchs like (eg.) Arnault (LVMH) would metaphorically slap Macron like they did on multiple occasions [0][1], and threaten to switch to supporting the RN. If they made Macron in 2017 [2], they can unmake him in 2026 [3].
It's the same story across Europe [4][5]. And any domestic capacity that could have remained within the EU is going to start leaving on January 27th [6].
Edit: can't reply
> how you get from IP law abrogation to 'quasi- nationalization'
IP Law protection is sacrosanct in any US trade deal, as we are a services exporter. If faced by actions like those mentioned above, we wouldn't be above retaliating.
This is why American tech companies successfully lobbied both the Biden and Trump administration to tamp down on any attempt on a Digital Services Tax by any country, such as with Canada [7] and the EU [8].
