I'm not attempting to prescribe a definition or usage of any terms. I'm simply describing a very common way in this these terms are already being used, and pointing out that your usage should probably be further clarified. If you wish to use "libertarian" to refer to something very specific, like perhaps the Libertarian Party in the USA, you're free to do so. I just think you should make that clarification, because people will understandably be confused by an unqualified usage of the term "libertarian." It is a term that is used very broadly by many different groups.

I also made no claims regarding the viability or merits of any of the viewpoints I was describing. That's not a conversation I'm interested in having in this context.
