Would you like to live in a city like this?
Nope. There is no 'guarantee' the centralized kitchen produces nutritious foods. Further, you the recipient have no way to verify with any ease the accuracy of any 'claims' of nutrition made by the centralized kitchen.
And if merely having a "centralized kitchen" guaranteed food safety, there would be no recalls of processed foods for listeria or salmonella contamination. A "processed foods factory" is exactly a "centralized kitchen", just with a different destination for the output food items.
