I must respectfully but firmly disagree.
A is A. A thing is what it is.
Of course. I would not deny this. But the undeniable fact that A=A (even though ultimately it is kinda a meaningless and useless tautology apart from pointing out that objective truth *does* exist, 'somewhere'), or that there are *some* things that are objectively true in the world does not mean that everything has an objective truth. Or that morality is objective. You don't need 'objective (concepts of) morality', btw, for morality to be useful, necessary, and *real*.
To pull so many claims of objectivity from tautologies and A=A seems a non sequitur.
The heart of the question of whether one 'is' or 'is not' a libertarian falls on the question of right and wrong and on justice. But there is no objective right and wrong. There is what society, for whatever reason, at whatever point in time, deems as right and wrong. The NAP, for example, is extremely useful - but it is not objective truth that 'should be' applied to all situations, all the time, and be followed rigidly - there are many conceivable situations, lifeboat scenarios, black swans, where the NAP breaks down, or would be insane, I would even say *immoral* to apply rigidly.
Ayn Rand rightfully took teachings from Stirner et al to talk about *rational* *self-interest*. This is something I absolutely agree with her on. But her philosophy breaks down in the face of this fact as well. For someone who talked so strongly about logical / philosophical / intellectual consistency - she was horribly bad at it, and would personally attack and ostracize, and get others in her circle to ostracize, anyone who pointed these things out or criticized her.
And Ayn Rand was a libertarian - regardless of whether she (or anyone else) likes it or not.
I will respectfully disagree with you. She was very libertarian on some issues, very unlibertarian on others. It's not so simply to call her, nor many people, straight-up 'libertarian'.
I think the central problem here is that many (including Ayn Rand) fail to understand that the term "libertarian[ism]" denotes a genus - not a species. As such, it embodies a generalization - not a particularization. Like so:
Any person who believes in & advocates for a significantly large[r] role for liberty in human society & affairs is a member of the "libertarian[ism]" genus. Within that genus, however, there are many particular species: Objectivist, Rothbardian, Friedmanite, Constitutionalist, paleo-conservative, minarchist, anarcho-capitalist, etc., etc., etc. Furthermore, some of these species may be in some way(s) dichotomous & mutually incompatible (such as Objectivism & anarcho-capitalism) - but only with respect to one another, not with respect to the over-arching genus. Forgetting this (or not realizing it in the first place) is what leads so many to incorrectly declare that "so-and-so" (or "so-and-so-ism") is not "really" libertarian[ism].
I can't disagree with much of this - but the fact is that some people do define and view 'liberty' and 'freedom' differently. Particularly, and especially when it comes down on issues of what constitutes 'just' (as in, justice) property claims. Through many, many discussions, I have come to acknowledge this. This does not necessarily mean then that we must have a State, or that other folks who see property differently than us are necessarily Statists - it just means that *subjective* views of morality, of right and wrong (particularly when talking about 'just' property claims) do indeed exist. Maybe not everywhere, but at the very least in some, if not many, or even most places. And it means that we should simply freely associate with those who are closest to us in our views in how / when we structure our society (hence my group, State Abolitionism).
The same thing goes for numerous specific "fault-line" issues such as abortion; "pro-life" and "pro-choice" are both "trees" in the "forest" of libertarianism - even though they are utterly irreconcilable with one another. Hence, a "pro-life" paleo-conservative and a "pro-choice" minarchist are both libertarians.
Well, I actually fall on the pro-life position myself, and take the more consequentialist approach *against* banning abortion. Abortion I view *personally* as morally wrong, deplorable, disgusting... but that banning it is a cure worse than the disease. You can't ban that. It is an issue of social and cultural degradation and the law cannot fix that - only ostracism and values. But I digress...
Which brings me to another part of my point. I can view abortion as morally wrong, and don't need claims of 'objective morality' to have this view. Some may disagree - say that it is 'morally right' and should be embraced. I think these people are disgusting and foolish and those who engage in it or think about doing it should be encouraged not to, I think a properly evolved market in process and technology can minimize the moral and human fallout in such a culture, and that those who engage in it should be shunned and ostracized throughout society.
