The academic tariff playbook assumes countries don't weaponize their currency and reduce their populous to slave labor. This is the world we live in and tariffs are the only defense against that.

I'm not sure what you're trying to say.
If another country produces goods with save labor (eg. China through excessive currency devaluation) a country that does not excessively devalue their currency along with them loses all their domestic production through outsourcing (eg. The US)
The only way to defend against this is through tariffs.
The reason the US has to play the currency devaluation game is because of China. This is why we're in this situation in the first place and why #Bitcoin was created to defend against this attack vector.
Russia for example has not played the currency devaluation game; and has sky high interest rates to defend against outsourcing. The result is a totally stagnant economy but a "sound" currency. The US cannot have the world reserve currency along with high interest rates (by default we should have the lowest interest rates) so we cannot compete in the currency devaluation game with China. Bitcoin is the mechanism that resets the currency devaluation game.
