So is her Objectivism.

If Rand were alive today, I'd probably respond by saying that as she identifies as a philosopher, she's (part of) the logos to libertarians' praxis. So, naturally there's going to be some sloppiness introduced into her conceptual ideal. That's there to account for the real world issues she didn't have to deal with alone at her typewriter, like how to get enough bodies to have a viable a political movement.

Furthermore, what she's describing in the latter half are anarcho-capitalists, which are a small subset of libertarians. In fact, many (perhaps most) of them would be very uninterested in being labeled as such, thinking of libertarians at best as minarchists.
