The point is that it doesn’t discredit the original criticism. The guy in the comic is trying to shift the focus from the systemic level to individual consumer habits, and to discredit anyone who doesn’t adhere to perfection. This is a common tactic the right uses, and no matter what level of ethical consumption you do they’ll either still say it anyway or switch to characterizing you as an extremist or some other tact, for instance, the various tactics used to attack vegans and veganism. There is good faith criticism to be made regarding ethical consumption, but there’s also bad faith criticism where it’s used to discredit legitimate criticism, which is what the comic is calling out.
