I guess the parents point might be that the price of soy bean then wouldn't have been a good bet, because any benefits from the shortage of animal proteins would surely have been un-done by the fact much less feed would have been purchased (for obvious reasons)? Demand may not really have risen.

My point was that market research that leaves off popular human protein sources is probably a bad idea.

I don't have a prediction if that will make total soybean consumption go up or down in this scenario. Substitution effects can be extremely difficult to predict.
