Yes, the characters are intended to be one dimensional. You'll notice all the characters have differences from each other in important ways, because they are meant to show how certain beliefs (and contradictions in beliefs) interact and have consequences.

Dagny and Rearden have internal contradictions, and it's not the point to find relation to them as people, but how their contradictions affect them.

The one sided villains aren't meant to be rich characters full of life, but people who carry out principles you here uttered in real life to their extreme conclusions.

The purpose is to take people at what they claim their values are and illustrate their implications.
