I feel like people who espouse this sort of view often wildly over estimate their chance of not ending up with a pointy stick through an important organ.
We don't do that because we don't like seeing women and children get their brains beaten out with a large rock over a rabbit haunch that the bigger ape wanted.
Because of the intermingling of law and wealth. If you don’t intermediate, then justice becomes the will of the wealthiest, and the market stagnates. The only way that evolution works is if it is the highest and only law, so we would be warring individuals killing each other for resources on the daily.
As soon as you add social organization, you disrupt evolution inside that social unit: it then becomes one social unit vs others…. We’ve already been down that road, and now we live in large, relatively stable social units we call nations.
Anything inside a social unit is subject to the monopoly of coercion that the unit possesses over its members. Evolution is short-circuited by the presence of external existential forces.
Making evolution work inside a social unit is equivalent to dissolving it.
What does that look like, practically, considering how many rich people were born into an abundance of resources? Their survival is not a measure of fitness.
