I certainly agree with you that tariffs and withdrawal from these internationalist trade schemes is step one back to sanity on trade. Tariffs are far superior to income taxation, payroll taxation, VATs, property taxes, etc.
Sowing the chaos is wrong and sinful. Totalitarian regimes are born out of disorder. Freedom is born from the order and virtue.
Instead of promoting international supervision of national currency we should protect the integrity of nation states. Use tariffs.
