Of course the calculation is meaningless?
That’s a wild POV. The markets have lost $11t in value since Trump took office and $6t in two days, with that last hit directly attributable to these tariffs and how they were both rolled out and explained.
The fact that the base calculation makes no sense and then the administration improperly implemented it makes them look like idiots, just as all of the talk of annexation makes the administration look like some combination of stupid and evil.
It matters, and I suspect you’ve been around long enough to know that. The markets certainly know it.
