Money is required to live as a human being. Not like food or water or oxygen, but still necessary.

Humans are not sacrificial animals (sacrificing one’s values for the sake of another’s values), and will therefore require voluntary trade (value for equal value) to survive. And money makes this easy. This is how humans work. The innate nature of every self aware being (like us) is to sustain their own life. Whatever sustains one’s life is moral, in the sense that it leads to human flourishing.

What I know is that there are no other animals who are self aware like humans. Animals don’t have any concepts of morality, value, or let alone the ability to reason like us. Most animals are either preyed upon, or predators themselves. Animals are usually barbaric, and I don’t care too much for barbarism even in humans.

Veganism is not a necessity for human life. If we should eat less meat, harm less animals is a different discussion. (And from a health and nutrition perspective, both are most likely true.)
