I never made that argument that anything is good or bad because nature has selected strongly for it. That's essentially an appeal to nature. Nature strongly selected for using animals as a main land transportation mechanism for a long time, but hopefully no one would argue that therefore no one should have worked at discovering a better alternative.

Even if government is the best way to organize society at the moment, that doesn't mean it's unreasonable to look for better alternatives. But again, none of this has to do with the analogy to intelligent design I was making.
