You cannot "chug pills all day" and manage to live healthily. Your body needs calories, amino acids and digestive enzymes to break down and absorb the proper nutrients. It has been shown repeatedly that this is sustainable through a vegan diet. I find it rather dishonest when people reduce it to simply "food". "Oh, how is it unethical? It's just food." No, it's not. Without getting too preachy, sentient animals are subjected to unimaginable pain and suffering (and obviously death) before becoming that neat little piece of food on your plate. There [b]are[/b] ethical concerns here. Serious ones.
