The main benefits of free trade are in specialisation. People specialise in what they’re good in and trade for other goods and services. Specialisation leads to greater efficiency, meaning you can do the same with less, or more with the same amount. Notice the complete lack of the words domestic production or intellectual property.
The case for free trade is that in the long run specialisation makes us richer. Units have nothing to do with it. Metric or imperial, services and goods are what they are.
