I'm thinking about that one. I hadn't thought of it quite that way.
The idea that the country is at the mercy of whoever can provide the food is an extension of the idea that if you rely too much on very few players to provide the food the population needs, and something goes wrong with the very few players, the population's health is in jeopardy. That's the concept.
Or if you rely on other countries to provide your food, if you extend the core competency argument too far and give away your ability to produce food at all and rely on other jurisdictions to provide it, you are arguably putting the population at risk.
We're not saying that anyone is proposing that the nation go that far, but if you see the nation losing an ability to provide food and feed its own people, you start to ask those sorts of questions.
