Fwiw good quality canned tomatoes can be miles better than buying "fresh" tomatoes for the 8+ months of the year that they aren't actually in season (depending where you live in the world). Growers still grow them, but they're less sweet and less juicy. Canned tomatoes also break down way better for sauces. I agree with your overall point, and almost all of my fruit and veg come from farmers markets, but tomatoes generally don't for both cost and quality purposes.
