Pricing in externalities (such as national defense impact) is a basic function of economic policy.

I searched 'economics 101 strategic industries' and found this[1] within 30s which includes an overview of 'national self-sufficiency'. It presents the standard argument, including the parts you claim the standard argument ignores.

I personally favor decentralized planning over markets, but I find it unnecessary to slander economics.
