I can't steelman the case for high tariffs, but small tariffs make sense to me.

There's a trade off between economic diversity and comparative advantage, and a balance is better than being at either extreme.

A 5% cost advantage might be sufficient for a company to offshore production of medical supplies, but is that minor cost saving worthwhile versus the risk of a shortage in war or pandemic?

Automation is reducing labor cost advantages, and converging unit manufacturing costs globally, so more and more industries are falling into this "slight comparative advantage to offshoring" case.
