What was Ayn Rand’s view of the libertarian movement?

Ayn Rand was opposed to the libertarian movement of her time. In 1971 she wrote:

For the record, I shall repeat what I have said many times before: I do not join or endorse any political group or movement. More specifically, I disapprove of, disagree with and have no connection with, the latest aberration of some conservatives, the so-called “hippies of the right,” who attempt to snare the younger or more careless ones of my readers by claiming simultaneously to be followers of my philosophy and advocates of anarchism. Anyone offering such a combination confesses his inability to understand either. Anarchism is the most irrational, anti-intellectual notion ever spun by the concrete-bound, context-dropping, whim-worshiping fringe of the collectivist movement, where it properly belongs.
