>Existence is infinitely richer than our descriptions of it. So, rather than cling to reductive explanations that only ‘close’ life’s possibilities...

Eh, sure you can dig into anything as deep as you want to go. To look at any economic detail, you could follow that into sociology, psychology, neuroscience, biology, chemistry, nuclear physics, and quantum mechanics. Or you could look at any of the potential layers built upon economics. So sure, "infinitely richer" in the sense that is all this stuff is complicated.

....but the solution is to reject reductive explanations? They just pointed out that there's an infinite amount to know about anything. How do you wrap your head around anything? You first learn a simple version. "Things fall down". THEN you learn about orbits. Then you get into spacetime. Of course you reduce it down to something manageable. You learn about edge cases and expand your knowledge, but you have to start somewhere.

"Clinging" to the simple explainations isn't a good idea. It's not going to get you into orbit. But learning about orbits doesn't mean things stop falling down.
