Not everyone in the world can afford "ethical meat" but they still need to eat nonetheless. This is one of the things I have never understood - people that are into concepts like "ethical meat" tend to be left leaning, and people on that side claim to be compassionate toward the poor. Yet it appears from your comment that if you had your way, you would use regulation to force the costs of eating up, which would dramatically affect the ability of poor people to eat.

You can’t simultaneously claim to have compassion for poor people and advocate for regulations that will make their lives more difficult and expensive than is absolutely necessary.
