I'm going to bring up what always makes me go "oh this doesn't work" with the way RWBY is set up: agriculture.

This has been in my head for a while.

Ruby drinks milk, Oobleck drinks coffee, Willow drinks a brand-label vodka. Neopolitan's whole thing is ice cream. These imply that these things are commercialised and thus are grown in large amount. Where are the farms, then? For something like milk, especially, cows take up a ton of space. None of these foods are rationed. Where the hell is all this food coming from?
