Regardless, my points stand independently of what he thinks.
You listed some drawbacks of tariffs. I don't deny there is a cost, but I already said I believe the price is worth paying. Tariffs are stopping US companies from enabling China industry & technology with short-sighted, Wall-Street-oriented decisions. Our economy is now consumer driven, not manufacturer driven. Tariffs seek to reverse that (or at least slow down the progression).
We beat Germany and Japan because of our manufacturing prowess. We no longer have that. We do have a tech advantage. But guess which wins a war of attrition...one Panzer or 10 Shermans?
But re tech: US companies are licensing our tech into China so China corporations can have a non-US supply chain (China's China-only supply chain requirement being their version of tariffs). Tariffs are a weak attempt to slow things down. Don't let the fact that Trump is the person doing this require you to believe it is a bad thing. For national defense, this is necessary.
