Great point. Humans still legally rape babies and own slaves. Laws do not curb bad human behavior, and we have not used legislation to protect people and criminalize anti-social acts. There has been no human progress over the past few centuries, and enacting more laws, rules and legislation to make the world fairer is not possible, because of human natur- oh wait. I'm an idiot! The "human nature" argument is nonsense!

I'm reminded of an Arthur C. Clarke story, where he pointed out how you can create a fair, just economic and political system with a simple USB drive containing a word document full of societal rules. In his story the USB drive would go from planet to planet, and be codified by people on these planets as their new societal laws. Rules, the story argued, guide how socioeconomic systems behave, and these systems in turn shape people. ie- you want a better world, you get smart people to push smarter laws.
