alt Hacker NewsNot to my understanding. Libertarian protections are from my understanding all about the quantifiable damages that were done by any given action. They don't usually go beyond that.
That's why most libertarians would be in favor of blowing asbestos insulation with the thought that "well, eventually the mesothelioma victims will sue which will stop the practice". You couldn't preemptively sue, however, as you don't have any damage you could demonstrate until after the cancer starts.
There might be flavors of libertarians that aren't that way but it's my understanding that environmental protections is one of the weaker aspects of the libertarian mindset. Especially since it simply doesn't account for "all the damage is done and the people that did the damage are now gone".

(Most) libertarians still support addressing externalities.
One common libertarian solution for something unproven would be "it's your job to purchase insurance for this new way of doing things, and convince an actuary that it's safe; the insurance premiums will stop you from taking risks with unproven technologies without appropriate precautions/testing/etc".
You're describing Corporatist Libertarians.
Traditional Libertarians: No organization (government or otherwise) should be large enough or powerful enough to infringe on anyone's liberties.
Corporatist Libertarians: No government should be powerful enough to infringe on the liberties of corporations.
Corporatism has taken over about 50% of the Democrat, Republican and Libertarian parties. They're what people usually mean when they say "moderate" in the US, and why no branches of the federal government have an approval rating above 33%. It's also why things are going downhill so fast: It doesn't matter which party is in power, even if they've got a filibuster proof majority and all three branches in their pocket. Their corporate faction will still be powerful enough to block progressive and populist legislation.
You are perhaps confusing libertarians with anarcho-capitalists. Ancaps are a subset of libertarians. I think among other right-wing libertarian varieties there is a broader spectrum of beliefs, and left-wing libertarians generally would not support anything that pollutes the commons (although they would disagree about the best means of preventing such pollution).
> environmental protections is one of the weaker aspects
That is probably why we are not on the same page here. I'm thinking in terms of the actual harm. Someone rolling coal near me is causing violence to me. The damage to the environment is more difficult to quantify, and that is not the angle I would approach it from.
