This is orthogonal to the main point which is that just because we are capable of eating something doesn't provide a moral justification for eating something. It is extremely clear from data and example that it's possible and actually easy to live a happy life on a plant-based diet. This means that eating meat is a choice, and many would say it is an overwhelmingly cruel choice.
Morality is a relative and personal thing. It is also very clear from data that you can live a good life while eating quality animal products.
Some may prefer to do it for personal pleasure, but also ease of life, or cost, which allows them to have time for things that they believe are also moral. Such as taking care of their children, working, and so on.
