You are missing the key quality for which industrial scale produce has been selectively bred over the past century: shippability. The ability to be placed in a box and moved thousands of miles without falling apart is the paramount quality of mass produced produce. Go to a farmer's market, be anything but delicate with a large heirloom tomato and you will understand what I mean.

Since growing myself, I have found a whole new appreciation for vegetables. For all these reasons the stuff you buy in the shop can never be as good (at a reasonable price anyway). It takes very little expertise to grow vegetables yourself, that are better than 90% of the stuff you can buy in the shops.
