I think you definitely make a good point, but I suspect the key differentiating factor for most customers switching to "fast casual" is simply the taste. There's no denying the ingredient quality is a lot better; the food is just more appealing. Eating Taco Bell for 10 years and then trying Chipotle is probably sufficient to convert most customers who can afford to eat at Chipotle a lot, regardless of health or sustainability impressions.
