The falsifiable model of human behavior lurking beneath the fiction here was expounded in To Spread Science, Keep It Secret. Trying to refute that model using details in the work of fiction created to illustrate it isn't sound.

EDIT: For what it's worth, this is also the same failure mode anti-Randists fall into when they try to criticize Objectivism after reading Fountainhead and/or Atlas Shrugged. It's actually much cleaner to construct a criticism from her non-fiction materials, but then one would have to tolerate her non-fiction...
