I think the fact that they are not healthier (by fat or calorie content, I forget which) is a major deterrent. I think another minor item that's overlooked is that there are a number of people trying to avoid "processed" foods, and there's few foods on the planet more processed than artificial meat. People interested in their health and this line of thinking will take beef from a local butcher over shrink-wrapped frozen frankenfood that is pretending to be beef. I'm not much of a meat-eater. I probably eat meat maybe three or four times a month. But when I do, I get something from the farmer down the street who is happy to show me her cows, pigs, and chickens, and not something from a cardboard box that came from an industrial factory.
