Services are ignored by Trump for precisely the reason you mention. The big question is: What will other countries do, like Germany, who tend to export goods to the U.S. but import services. Right now, those are the countries who would rather prevent this thing from escalating, but if escalation it must be and they run out of ammunition within the scope of tariffs on goods, where will they go next?

Tariffs on services may also be less popular with the citizens. It's not obvious that the locally produced fridge is only cheaper because of tariffs. It will be more obvious that everyone non-EU based pays more. It will also be harder to control (how will EU extract tariffs for payments I do to companies with no EU presence?)

But I don't how much about it, maybe these are already solved problems. After all VAT already exists and faces similar challenges.
