What is the main argument made against tariffs?

1. The case against tariffs starts from what free trade is meant to achieve. 2. Free trade lets the principle of comparative advantage work most efficiently. 3. Tariffs discourage free trade and so block that principle from working. 4. The second argument against is that tariffs raise prices and cut the purchasing power of consumers. 5. Collection speed and currency reserves are not part of the case against tariffs. 6. Tariffs do apply to goods trade in practice, so impossibility is not the objection. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 3 "Competing in the Global Marketplace", section 3.3 Barriers to Trade_
