Well, there's still the issue of "living on the products of the plant kingdom." The only thing I can think of that's similar would maybe be recycled leather. I still think ethical vegans would have a problem with it, and I don't see this changing the opinion of anyone doing it for health reasons. I think environmental vegans are the most likely to buy into this..if it even becomes an efficient way to produce nutrition/calories. I could certainly see some more pragmatic organizations throwing their weight behind it.."if you must eat beef, at least eat this kind of beef (but consider X, Y and Z as even better alternatives)."
