That would be a strong, compelling argument, but it would be emotional only. Logically we gain nothing from improving animal rights, except insofar as the meat may be healthier/tastier or that we don't feel so bad. The first may be worth it, the second can be achieved by hiding factory farming more efficiently. Of course if you think animal suffering is bad, that is a different pov, but why should you?
