Nature doesn't work like God.
God creates a world and peoples it with his chosen flock.
Nature creates the selfish gene, loves biodiversity and creates niches
for life wherever it can; and it doesn't care if one life form has to
suck the brains out of another in order to survive and thrive.
You could create a society like Sparta; enslave the surrounding peoples,
march up into Attica and destroy the crops there in the new year, and
then march back home in autumn to supervise the harvest taken in by the
helots.
But nature would be plotting to implant alien life forms in you; and the
best laid plans of mice and men would be toppled.
The best political constitution to handle that, to deal with change, is
democracy; a democracy that represents every mutation from the norm that
nature can throw at us. It's a mishmash, an ideological non-starter,
something that God would never have dreamed of; but it works.
We live on a violent planet; with violent weather; with meteorites that
could wipe us out; in the corner of a minor arm of the Milky Way Galaxy.
Our existence as thinking beings appears as unlikely as a mountain made
of chocolate and topped with meringue; but here we are.
Beware of human nature. We are beasts. And we are far more numerous than
those rational philosopher kings.
Build a palace of glass for the best, and we the excluded will rip it down.
