the fact is that any 'good' coming from being alive cannot make up for the 'evil' that it costs if one is arbitrarily strict - the pain and injustice of cows dying to make food, the environment disturbed to ensure sufficient square footage of crop growth, the carbon emissions required to maintain a population above a certain level. In order to stay alive, in the face of an arbitrarily strict moralist, one must defiantly and violently insist on living. Don't do better, do worse.
