I question whether it is possible to be "fit" in this analogy, or just lucky.

Also, let's not forget that "fitness" and "conformance to our values" are separate dimensions. It is not necessarily the case that we humans want to optimize companies for their ability to withstand once in ???? year events without government assistance. Companies optimized along such criteria would be more fit for an environment where government assistance doesn't exist, but crucially that is not necessarily the actual environment that companies exist in in the real world. And it is not obvious to me that the citizenry benefits from companies optimized that way.
