It’s not a “with or without” question. Is a “do we want to rely on the behavior of a country like Russia or China, or do we want to assume that these supplies are risky so let’s model and mitigate that risk” question.
It kinda was a with or without question in the parent comment, that we will starve and the planet will die if we use monocultures. Hence my comment. Of course I agree with you that agriculture can be more robust, but 'native Americans did this technique with low intensity method to feed a small population so we should' is about as facile as the 'trade cars for horses' example
