If infra for food transportation does not exist then the point is even more valid.

If I have village where no food can be imported and limited amount of agricultural land. If I grow khat how am I going to feed my family if outside food can not come in ? Will the villagers be willing to pay more khat even when food is scarce ? I think I am missing something.

Dry food is extremely easy to transport. For the farmer, they are only growing cash crops if they can sell it outside of village, but if they sell it that means they can also import food.

At worst it might be raising food prices for non farmers, but farmers are going to be strictly better off.
