The eternal problem of "the general public" is that they're a product of their material conditions. They don't emerge from the soil and engage with the world on first principles.
When you grow up in a community that has been heavily privatized and financialized, socially owned and operated community functions have to be developed from the ground up rather than inherited. Any kind of proposed social change will grow out of the body of the system that came before.
Libertarians grow up in countries where it is easier to believe in the end of the world than the end of capitalism.
I don't understand why you think that is a contradiction. You both agree there's a spectrum between the two. Technically, if you're not 100% authoritarian you have a greater-than-zero alignment with libertarianism.
Now, if you're trying to say landing somewhere in the middle of the spectrum means you're neither, then I tend to agree with you (labels suck). However, I'd take it a step further and say that nobody is going to be the 100% perfect embodiment of either end of the spectrum, and therefore, no true authoritarian or libertarian exists. I think, to say either one of you is wrong is just arguing semantics.
Edit: ok now that I'm getting downvotes I feel I need to explain: the conventional usage of the word libertarian is not commensurate with it covering such a wide range of the political spectrum. Usually we mean people who favour mildly anarchistic views (minimal governmental institutions, low taxation, low intervention). Representing that niche as half of the political spectrum is highly disingenuous
the word libertarian literally does mean what I'm telling you though . What your experiencing is that your personal definition is not matching up with everyone else's reality. You've just been misinformed and have only been exposed to a subset of libertarian ideals . To put this in an analogy it's like if I said truck and you assumed I was talking about a Ford F-350 when in fact I'm referring to all trucks. From tiny k trucks to 18 wheeler big rigs
Oh I'm fully aware. I'm not a socialist though. I still think capitalism is the best model for innovation it's just the current system is geared to fuck the small mom and pop and only benefit massive conglomerations. If I was hypothetically in charge I would fully cut corporate welfare and redirect all of that directly to proper funding of essential services and safety nets and infrastructure. If your company requires government handout money to run, it should go under. That's the capitalism I want to see.
