It's economic, but does the creation of economies that provide the material needs for the sustenance of society by necessity involve utility maximization?

What about ancient economies like the Greek oikos, or the manorial system?

And is utility maxmization fundamentally an emperical matter or a normative matter?

If the latter, are not the illusions of economics to be a natural science rather than social philosophy misguided?
