In this system, the more freedom people have to trade with people in other countries, the better off they are (and the freer they are).
Look at the United States. We have 50 states that have totally free trade.
But suppose we didn't. Would the people of the United States be wealthier and better off if each state treated its economy in isolation, and strove for the ideal of equal trade between each state? Would Maine need to freak out if they discovered they had a trade deficit with Rhode Island and that they shipped far more lobsters to Rhode Island than stuff they got back from Rhode Island?
Of course not.
Suppose that lawmakers in Oregon noticed that Nike was a valuable employer in the state, so they passed a law putting a high tariff on shoes made outside the state and totally ban shoes being imported from Texas because they don't like Texas' politics. So when a shoe buyer in Oregon goes to the store, they find that most the shoes on sale are Nike, and the other brands are priced much higher because of the tariff.
But a shoe buyer in Idaho goes to the shoe store and finds that in addition to the Nike shoes on display, they can choose from many different brands at all price levels and from all over the world.
While the Oregon law may seem to protect jobs for Nike, who is paying the price? Who is "freer" and "wealthier", the consumers in Oregon or Idaho?
Ultimately, "countries" don't trade with each other. It's individuals and business who trade with each other, and when people and businesses are given the freedom to trade, they are able to make the best decisions for them on what they want to buy and what they don't want to buy. The economy is too complex for any government to "manage" millions of trade decisions. Give the people the freedom to make their own choices, and that will bring the most wealth to a country, even if it puts pressure on certain companies or industries in the short run.
