One thing that Factorio drilled into me was compression. It's easier (=cheaper) to transport compact processed goods than bulky raw materials. In the real world, shelf stability is also important, it allows cheap-but-slow modes of transportation.
Keep in mind that shelf stability refers to the food safety of the product, not its quality. One of my friends used to work at a candy factory, and the difference between freshly made gummy bears and the ones picked at retail (that have been sitting in a warehouse and on shelves for a few months) is very large. One of them is filled to the brim with flavor, while the other one is much less flavorful and drier.
They're both edible and safe to eat, mind you, but it was much better to get fresh ones. Or not eat candy at all.
I think it's like being a native american that has never have been exposed to christianity. Why spoil something you don't truly want to know that could alter your worldview haha!
