Ayn Rand's philosophy:
Yes indeed ... free yourself and serve only yourself and die alone like Ann...
Meanwhile a lone man should hunt woolly mammoth with a stone spear he invented and made ... and then invent the knife that can cut through hide so he can eat his prize while warding off dire wolves that hunt cooperatively in a pack ... while avoiding saber teeth and bands of pesky hominoids ... then later, he can spend billions of man hours inventing and assembling the parts, math and technology to generate electricity from falling water, after he builds the hoover dam.
