> Entities the size of the US or the EU are capable of producing most or all strategically important products internally
The US can internally produce: food staples, fossil fuels and nuclear fuel, most (but not all) industrial chemicals and construction material, defense systems and major military equipment, generic drugs and many medical devices.
However, vulnerabilities exist in: semiconductors, rare earth minerals, speciality chemicals and pharmaceutical raw materials.
Even if the EU were a country, it has high self-sufficiency for: temperature agriculture, industrial chemicals, some aerospace and defense components.
However, it is import dependent for: energy, specialty metals and rare earths, pharmaceuticals, high-tech electronics and semiconductors.
Lastly, what about the remaining 167 countries in the world (195 - US - EU)?
90% of the world's population live outside the US and EU.
Trade is really really important for human flourishing.

The US used to produce nearly all of those things and would benefit from having the industrial capacity to process rare earths even if some of the mining happens in Brazil or India or Australia.

They would then have the option to buy any of them from the US, the EU or China instead of having only one of those monopolize global production.
