I think the story is falling apart here.
The butcher exists because of demand. Killing the butcher doesn’t kill the demand.
And, if there is a “supermarket” factor, as Velda puts it, then there must already be a supply chain, along with competition!
Plus, as Jake has already pointed out, Endtown has a food supply, so what guarantees that the meat eaters will starve?
My final concern: Is this devolving into a story of the virtues of vegetarianism and veganism over the “rest of us”?
