 If buying wrongfully-produced meat is wrong because it produces more wrongfully-produced meat, is it wrong to pay rent in the rent case? Is it wrong to buy a vegetarian meal at a restaurant that then takes your money and uses it to buy wrongfully-produced steak? These are questions for productivists’ moral claim. There are further, familiar questions about whether it is wrong to produce wrongdoing when one neither intends to nor foresees it and whether it is wrong to produce wrongdoing when one does not intend it but does foresee it and then about whether what is wrong is producing wrongdoing or, rather, simply producing a bad effect (see entries on the  doctrine of double effect  and  doing vs. allowing harm).
