That’s the thesis put forth in an essay over at The Federalist. It concludes:

Here’s a challenge, then, for sci-fi writers who dare to think big and reimagine society, if that’s what Kreider says he wants: Imagine the world as it might be if humanity had never made the collectivist error in the first place. Imagine history as it might have been if, say, Plato had advocated strict property rights and individualism instead of wanting communal living and “guardians” who oversee the rest of us. I think we might by now be immortal and living among the stars.

Read the whole thing. I tend not to agree with him. Odd that the photo at the top of the piece pictures some Heinlein books.
