I'd argue that centralization allows a scale that otherwise wouldn't have been possible, but at the cost of added fragility and externalized costs. We produce way more corn in the US today than we could without a centralized industry, but we do so by subsidizing the hell out of an industry that is driven only by how much volume of corn is produced. Nutritional quality of the food produced is ignored, damage to the land is ignored, damage to the broader environment is ignored, etc. We grow a small amount of corn on our land. We absolutely don't have as high or consistent yields as an industrial farm, but we also don't spray any poisons on the land and if the soil health was being negatively impacted we would know it pretty darn fast. Rain water from the corn patch runs down into the pond our cows drink from, another reason we wouldn't use poisons on the land. All of these are considerations one will likely make at a smaller scale that just won't happen with a centralized system driven by one or two primary goals (currently that's just money).
