A squirrel will spend energy to collect nuts and bury them together in the ground, rather than having them scatter and roll and blow willy-nilly. A person is constantly sweeping up the dust inside their house, painting and repainting the trim of their windows, and organizing the cables in their desk drawers.

Life can most certainly be viewed as a counterforce to entropy. Certainly at the philosophical level, but why not at the genetic level too, reproduction being the repeated organization and duplications of chemical bonds from smaller constituents.

I certainly see my life as a constant battle against entropy, an adult's life consists pretty much 80% of putting things in things.

>I certainly see my life as a constant battle against entropy

lets consider an amount of non-live matter equal to your mass. That pile of non-live matter wouldn't be able to generate amount of entropy that you will generate during your lifetime. Your actions of "battle against entropy" is a more faster way to increase total entropy. That is the reason of live matter existence - it is a faster way to generate entropy, and thus it is direct result of the 2nd law which states that any system evolves among the entropy maximization gradient. And live matter organizes into more and more complex systems - bodies/colonies/organisms, smarter organisms, societies - because that generates even more entropy than the simple set of constituent parts would generate on their own. Compare entropy generated by a 10 strong tribe in Amazon and 10 regular Americans or Europeans (bonus point - consider that the civilization complexity allows for 100 "civilized" people all actively generating entropy where hardly 10 could barely survive without the civilization). One can notice that intelligence arises as the power multiplier of live matter entropy generation capability.

Sure, as long as we qualify the terms correctly. That is, you need to decrease the resolution of what you mean by 'entropy' because each one of your examples actually increased entropy moreso than inaction would have.

Regardless, this goes against the author's point, because in each case 'work' needs to be done to reverse the entropy of a local system (e.g. scattered nuts) at the expense of the larger system (squirrel heat emitted into the universe)

Sure, with proper qualification that is one way to look at things. This works because of the resolution that we care about. Namely, we don't care about heat generated from our bodies, or smart phones, or nuclear reactors, accelerating global entropy, but we certainly care about dusty rooms.

Again, it seems like the author disagrees with this view.

I submit to you that you did not get the point the article is trying to make because it was exactly this. When considering the animal expending work as the system, it's entropy doesn't decrease because it isn't a closed system. You can then retort that the 2nd law concerns a larger closed system, but you can keep playing that game until the 2nd law essentially becomes a tautology, and becomes useless in understanding the system at hand.

I don't know if the author made this point explicitly (he hinted at it at the end), but one needs to actually know the details of the system under consideration, and very general laws can bring some level of context but will be limited in terms of the actual relevant or useful insight one can glean.
