Libertarianism is a anti capitalist, socialist and very left wing ideology everywhere except in the US where it apparently has been co-opted by insane people with the opposite beliefs.
so you fall into the camp of not knowing the consequences.
the issue inherently is that the power imbalance of stuff like wealth inequality, coupled with material conditions, always end up curtailing the freedoms of those who are not on top, ironically making them less free (bit of an irony, eh?)
Not sure what consequences you are talking about or what you are even arguing about. I agree with the second paragraph as would most libertarian outside the US so I'm like double confused.
that a lack of government does not equal an increase in freedom, instead it just allows those with power to exert it more directly upon the less well off.
Yet at no point did I ever mention any outcome of any libertarian belief or even mention if it was superior to anything. So again: How does that connect to my point?
Also I'd suggest you read the wiki, even that ain't true: Not all libertarian ideologies want to abolish the government. But that's beside the point.
