If you want to save money then cooking bulk foods at home might make sense, people just need to make sure they're really calculating the costs properly. If you want a balanced diet and varied menu, then it can be expensive and labor intensive. If you want to save the environment, then you should reconsider your whole diet. Reduce meat intake and make smaller meals with more environmentally conscious ingredients(likely more expensive). Regarding leftovers, plenty of people put restaurant leftovers in a container and take them home to eat later. The people who don't would likely waste food at home too.
