That’s one way to define “local,” and in fairness to you, it is the most popular. But the other way of looking at local production - not unlike times before globalized agriculture - had one’s diet actually match the climate available. Perhaps tomatoes don’t grow where you are, but surely something else did: very few places were founded without an agricultural/fishing base.

On a global scale, the huge (emissions) efficiency of loading a single enormous shipment of produce is only true on the receiving end, a number of farms far away all ran their own small deliveries to a depot for shipping at the start of the chain. There is no magic turbo-carrot-farm that harvests the world’s supply in one go.
