I actually find those arguments based on taste to be some of the weakest and least compelling. I agree with Kingsolver that in general, produce from the farmers' market or from my garden does taste better, but in the balance it's not nearly enough of a difference to make it worth the effort, or especially, worth the self-righteous indignation that she spends on dissing bad tomatoes.
Your example of the strawberries also seems germane here. I'm a big enough klutz as it is and have enough trouble keeping my clothes clean: most of the time I'd rather, in fact, not have to worry about dribbling juice on my shirt when I'm eating strawberries. Similarly, my kids snack on "baby carrots," another target of Kingsolver's scorn. Surely that's better than their snacking on Doritos?
I remember when I got used to drinking skim milk. I hated it for a couple of days, it "didn't taste right," but now I'm so used to it that it's whole milk that doesn't taste right. Taste preference is somewhat malleable and rather than embracing one's inner picky eater in the name of sustainability, I think there's a lot more to be said for getting over oneself and getting used to eating foods that one doesn't necessarily think one likes.
