There is a fundamental problem with slapping up tariffs with reckless abandon. After putting out enough tariffs, you find that all you have done is erect a trade embargo around your own nation.

Tariffs work if they are few and targeted. A tariff against a rogue nation as punishment for an invasion or covert nuclear program? That works, as you can effectively isolate the offender. But if you apply tariffs broadly, it soon becomes obvious that it is you who is the outsider, not the nations you are tariffing. All the nations you tariff can simply trade with each other and ignore you entirely.
