Well, to me ethics is just a more fancy name for morality. Now, if you want to avoid claiming that libertarianism is objectively good, or that it is an objective standard, that’s fine. I don’t want to force my moral standard on others. But what am I supposed to do when others try to force their standards on me ?
Anything you please. That’s what I do.
True, but libertarianism would drastically minimize life-boat scenarios, so libertarianism doesn’t really ask for self-sacrifice. Yes, you can argue that for people who like to take advantage of their neighbors libertarianism tries to impose an ‘unnatural duty’…
I actually think that it is more the case that libertarians want others to feel a moral duty to ‘respect’ liberty. I believe it would simply be enough if people generally appreciated liberty. ‘Respect’ or ‘deference’ in any absolute sense is for fools, though. Liberty is only so precious as I make, and only so near as I hold it.
