I believe the state is capable of unique evils, against individuals, communities, and society broadly. Since abolition is not feasible for a variety of reasons, I think the power of the state should be strictly curtailed. More generally, I believe restrictions on individual liberties are much, much more morally repugnant than inequalities.
(I
generally refrain from calling myself a 'libertarian', just because on the Internet that invariably gets interpreted as 'anarcho-capitalist' -- which I am not -- but it's not a label I wholly reject, either, and I think it would be fair to call me a fellow traveler to libertarianism, or something along those lines).
EDIT:
Well, this forum seems to think I'm an authoritarian because I believe the state has a role in protecting people against their own worst impulses and encouraging them to be moral.
Another way of putting this would be that I disagree with this post with every fiber of my being (and frankly find it horrifying). I think history shows that state-led morality invariably leads to genocide and state-led protections invariably lead to slavery. I am a libertarian because I believe the state is inherently immoral, and people have a role to play in discouraging it from taking as many actions as possible, and certainly in discouraging the state from holding itself up as a source of morality rather than depravity.
