I disagree because they're not smart enough to enjoy their short and simple lives, so the enjoyment our lives get via eating them takes precedence.
This is a very fascist position, though! I could say the same for a human on life support who's gone through brain death (really, a lobster's smarter, at that point). Although perhaps that's not really that bad, albeit macabre. Perhaps, one day, we'll lab-grow meat, maybe our own, to eat, just to see what we taste like. That's equivalent to consuming non-lab-grown but also unconscious human tissue, I think. BUT SCARIER, this same line of thinking might lead to much-vaster-than-human intelligences deciding we don't have rights and that it's okay to eat us!
Am I okay with being eaten by a hyperintelligent being to whom I have the status of a lobster or a cow? Maybe. Because I really admire a being like that. Maybe it could effortlessly convince me to surrendering to being eaten with arguments more creative and compelling than a million Shakespeares could pen up, effortlessly, like some Saruman-godthing[0], because that just goes with the territory of being that smart! But, short of that, I'd try to run away, and many people don't share my ambivalence...
Ethics is difficult. But chicken is tasty.
