Trading off efficiency for security is not wise unless you are in war. The same applies to supply chains.

By the time you are in a war it is too late. Far better to be prepared.

Its not just war either, as the pandemic showed. Trade disputes that lead to sanctions, natural disasters, and lots of other things require the same security.

Its worth paying a bit more for the security, for the same reasons people buy insurance.
