Libertarian thought is complex, non-static, and (importantly), non-monolithic. This is especially true for the relationship between people, government, and corporations. The generalizing statements in this thread reject vast swaths of ideas for no reason at all; even ideas that generally agree with the ideas in the thread. My guess is most people hold in their minds a caricature of libertarianism informed either by "that one libertarian guy from college" or social media postings. That's somewhat deserved, but also a shame.
Many people associate the word "libertarian" with right-libertarianism, which is the predominant form of libertarianism in the United States. Ayn Rand's philosophy of objectivism is right-libertarian.
On the other hand, left-libertarians oppose capitalism while supporting personal property rights. Left-libertarians and right-libertarians find common ground in rejecting authoritarian governments.
Libertarianism comprises a diverse collection of views that aim to advance individual freedom, and anyone who is not an authoritarian is likely to agree with some libertarian principles.
