One child describes his parent, and the teacher concludes that this parent is a fine philanthropist. Eventually, however, the teacher learns that the parent is giving away other people's property. So the teacher concludes that her student's parent is a thief. The punch line is that the parent is the mayor.
To which I responded with a succinct comment:
Mayor:thief :: juror:vigilante
Institutions make a difference.
He never did reply. Perhaps the thought requires further unpacking. See my discussion of three conceptual errors of libertarian ideology:
(3) It conflates personal and institutional action. This is the difference between vigilantes and magistrates. Just because it would be illegitimate for your neighbour to do something in their role as an ordinary citizen, doesn't necessarily mean there's no legitimate way it could be done.
A well-ordered society is governed by the rule of law. This means that there are institutional processes to govern certain classes of action. The outcome of a just institutional process -- whether it be a guilty verdict, or minimum wage legislation -- has a different normative status than the corresponding action of a neighbour who takes it upon himself to unilaterally impose his will on others.
There are good pragmatic reasons to favour some libertarian policies. But the moral ideology ("taxation is theft") is obtuse.
