I'll clarify, freshness matters for safety in general and is impacted by proximity to source. I get my milk from a local dairy and live in a big cow state, but you can't buy raw milk here legally unless you own a share in a cow, which here also means you also have to be able to show up at the farm to buy it and that's not a thing for the city people without cars, or generally reasonable even with cars because mostly you'll have to drive at least 1-200mi round trip to get to the dairy farms. Our state may legalize it soon and who knows maybe I'll be able to get it delivered. Anyway, from DC to Boston there's about 1/6 of the US population and getting shit delivered from farms is hard there on the day to day. Generally only the boonies in big dairy states have milk delivery, the only thing you can usually get local on the north east coast is some seafood. I just wonder what the proposed solution to the proximity issue between producers and customers in a place that arguably can't really fit more farms in it while also maintaining a testing standard that accounts for shelf life and avoiding freezing to that might kill any beneficial bacteria if that's the main benefit. There's room for more Amazon warehouses because they're just building on what was already made dead industrial land covered in concrete and oil stains. Not so much for moving cows closer to people in the most densely populated places in the US.
