I agree with almost everything on that list, and I endorse switching out sugar for honey because of its higher functionality, but as much as I also dislike the thought of abstaining from coffee, we should really consider putting up something with more nutritional value, especially since we don't even know if they provide us with any means to properly grind the coffee (same reason why I favour flour over oats). We have to also consider that maybe, we won't have the opportunity to actually heat or cook food properly.
I suggest some kind of fruit instead of coffee beans. Maybe bananas, they are healthy, they are filling, and they are more versatile for cooking than other fruits. They would be a safe bet in case we are confronted with a situation of not actually being able to properly prepare the food, or at least not for a while (those fucktards they did mention we won't be provided with some things immediately), maybe we begin from scratch, maybe we have to earn shit or privileges like being able to use any kind of cooking utensils, whatever these fuckers come up with.
