What’s the practical difference as far as the appeal to nature argument you’re making goes? Humans lived for thousands of years on maggot-riddled meat, same as they did on parasite-riddled salmon.

Surely if it was good enough for us to live on back then, it’s part of the circle of life and should be totally fine. Right?

If one’s no longer acceptable because we don’t do it any more, then surely if lab meat gets established then we’ll look back at that parasite-riddled salmon with the same revulsion as we do the maggots.
