Free People, Free Trade: The Principled Case Against Tariffs

The case against tariffs is not merely utilitarian — though the utilitarian case is overwhelming. It is a case rooted in the most fundamental principles of individual liberty. When the government imposes a tariff, it tells you: you may not buy this product from this seller at the price you both agreed upon. Instead, you must pay a tax for the privilege of doing business with someone the government doesn't approve of. This is not free enterprise. It is economic authoritarianism.

The Liberty Argument

At its core, free trade is an extension of property rights and voluntary exchange — the same principles that underpin all market economics. When you earn money, it is yours. When you wish to spend it on a product — whether that product was made in Ohio, Ontario, or Osaka — that is your right as a free person.

A tariff is government interference in a voluntary transaction between a willing buyer and a willing seller. It is, by definition, a restriction on economic freedom. The only difference between a tariff and any other trade restriction is that the interfered-with party happens to be in another country. But your right to buy doesn't depend on the seller's nationality.

"The consumer is the one who should decide where to buy. A tariff forces the consumer to subsidize a domestic producer — it is a compulsory transfer of wealth from consumers to producers, enforced by the state."
— Milton Friedman, Free to Choose (1980)

Adam Smith and the Classical Case

In 1776, Adam Smith articulated the case for free trade in The Wealth of Nations:

"It is the maxim of every prudent master of a family, never to attempt to make at home what it will cost him more to make than to buy... What is prudence in the conduct of every private family, can scarce be folly in that of a great kingdom."

Smith's insight — that specialization and trade make everyone richer — has been validated by 250 years of economic history. Every nation that has grown wealthy has done so by trading freely. No nation has ever prospered through isolation.

The Bastiat Test

The French economist Frédéric Bastiat, writing in the 1840s, offered the most devastating critique of protectionism in his satirical "Petition of the Candlemakers." The candlemakers petitioned the government to block out the sun, which was providing unfair competition with its free light.

Bastiat's broader point was about the "seen and the unseen." When tariffs protect a steel mill, we see the steelworkers keeping their jobs. What we don't see — because it never happens — are the construction workers who aren't hired because steel costs too much, the factory that isn't built because materials are unaffordable, the startup that never launches because component costs are prohibitive.

The seen benefits of tariffs are always concentrated and visible. The unseen costs are always dispersed and invisible. This asymmetry is why tariffs survive despite being net-negative for society.

The Friedman Framework

Milton Friedman argued that free trade is simply free enterprise applied to international borders. He rejected the distinction between "domestic" and "foreign" economic activity as arbitrary:

• If California wine competes with French wine, that's free markets. If we tariff the French wine, that's protectionism.
• If Texas oil competes with Canadian oil, that's free markets. If we tariff Canadian oil, that's protectionism.
• If Amazon competes with Alibaba, that's free markets. If we tariff Alibaba's goods, that's protectionism.

The border is an arbitrary line. Economic principles don't change when goods cross it. If competition is good within a country (and it is), it is equally good between countries.

Friedman went further: he advocated unilateral free trade — the US should eliminate all tariffs regardless of what other countries do. Why? Because tariffs harm the country that imposes them, regardless of what other countries do. If China subsidizes steel and sells it cheaply to Americans, Americans benefit from cheap steel. China's taxpayers bear the cost.

The Hayek Warning

Friedrich Hayek warned that economic planning — including trade planning through tariffs — inevitably leads to the concentration of power and the erosion of liberty. When the government decides which industries to protect, it picks winners and losers. This requires bureaucratic authority, invites political corruption, and creates dependence.

The 2025 tariff regime illustrates this perfectly. Exemptions, exclusions, and modifications are granted through an opaque process controlled by the executive branch. Companies lobby for tariff exemptions. Political allies receive favorable treatment. The system has become exactly what Hayek warned about: centralized economic planning dressed up as patriotism.

The Moral Case

Beyond economics, there is a moral case against tariffs:

• Tariffs are regressive. They function as a sales tax that hits the poor hardest. No libertarian should support a policy that taxes a single mother's shoes at 48% while taxing a billionaire's silk shirt at 0.9%.
• Tariffs are crony capitalism. Protected industries gain at the expense of consumers and competing industries. This is not free enterprise; it is rent-seeking enforced by government power.
• Tariffs expand government power. The 2025 tariffs were imposed by executive decree under emergency powers. If the President can tax imports unilaterally, the Constitutional separation of powers is meaningless.
• Tariffs damage international cooperation. Trade is the greatest force for peace in human history. Countries that trade freely rarely go to war. Tariffs strain alliances and increase geopolitical tension.

What Should Replace Tariffs?

If the goal is to help workers displaced by trade competition, more effective tools exist:

• Direct wage subsidies for affected workers (cheaper and more targeted than tariffs)
• Expanded trade adjustment assistance (retraining, relocation, income support)
• Lower taxes and regulation to improve domestic competitiveness naturally
• Investment in education and infrastructure that benefit all industries
• Negotiated trade agreements that open foreign markets to American goods

Every one of these alternatives is cheaper, more effective, and less damaging than tariffs. The only thing they lack is the political appeal of a simple narrative: "them vs. us."
