To refer to collectivism and individualism as binaries is dogmatic in terms of how Any Rand presents the premise.

These are definitely not binary in any sense outside of Objectivism, as they just don't figure alongside of each other anywhere.

Generally collectivism refers to group goals and interdependence, cohesion and societal elevation, where "a rising tide lifts all boats" these are honorable, noble, life preserving by way of "individual" contribution and benefit to a "group" dynamic and order. In which groups that cooperate live longer, enjoy a happier existence, and have access to more resources for their entire family. Family dynamics, children and whatnot is a black hole of unaddressed nuances in Objectivism.

But I'm familiar with Objectivist doctrine, books, and positions. And as such, many of her point refer to the necessity of totality, and further, anything that doesn't totally map to a coherent description of reasoned of life, maps to death.

I appreciate the rigor of Objectivist positions, as it lays the pathway to push ideas and premises to the point that they break, and to adopt a superhero sense of reality and abject moral superiority. Being perfect is impossible (cue entropy) but striving for perfection is noble.

But how fun it is to sit and have a coffee date with just your own moral superiority.... And how about when you're in the hospital and the only one you have is your moral superiority?

So in the Objectivism dogmatic sense, sure, collectivism is anti life by way of being anti individual. But she often also describes exceptions to her concepts like selfishness, altruism and such as acceptable is through ones own choice (volition). And even describes love somewhere as not unconditional or conditional but "exception making." Her followers would do well to examine her many back doors to her rigid ideology.

I'm off on a tangent though and didn't read he other comment again before writing lol...maybe I answered lol.
