I rather hear what about it could work and what things need overthinking.
Well, I think it doesn't really need to be explained, it would be like pigfarms/stables, you feed the animals with corn, they grow up, they are slaughtered and you get milk, skin and meat. But after all, you must pay attention to what I wrote, that it would make producing bread, wine and maybe even sausages disappear. Just because why would you waste your corn on such if you have a much better option to choose? And we already have enough kinds of food, that's another thing to mention. There are many many things against, and only one thing with... Which is "it would be nice". I think it doesn't really need further discussions.
so just telling why it won't work doesn't really help at all..
Actually nobody said it won't work. We said it'd ruin the whole game and make other food types disappear. I think these aren't the same (at least where I live they don't mean the same).
