It's not aesthetic reasons though, is it? This whole concern is about neural tissue being actually harmful. The question is then one of how you separate the edible part from the inedible part. Given that you can never do this precisely, you're going to end up either playing it too safe and leaving edible meat behind, or going too far and extracting inedible cowbits. Then the question is: is it a bigger sin to run the risk of harming humans, or to leave behind a fraction of a percent of the cow as a safety margin? Thought about in those terms, the edible meat left behind would be used, just not as food.
