That's absolutely true. But while physical laws just exist, "economic laws" are a complicated combination of biology, psychology, social norms, the legal system, etc. You can tweak the rules, but you can't run calculations that predict the results. Some of those legal arrangements might be unjust, but their results might be net-good all the same. We can, and should, keep evolving the social bargain, but upending it completely is very dangerous.
