Do you stand behind that position with regard to all regulation, in all its forms, as applied to all industries and entities?
I'm going to go out on a limb here and say yes. I'm sure you'll find some edge case that will make me think twice about that position, but hey, why not. That's what were in this forum for, debate, right?
I don't think what I would present would be an edge case, but rather fundamental. I don't think its appropriate that libertarians (or a large portion of them), choose to solve the problems by arguing the problems do not exist. That is not a solution, but a politically motivated decision to ignore science when it's apparent that addressing the problem would in fact require regulation if the problem existed.
Let's assume two possible scenarios:
1. The scientific data is correct, and the problems are real. I am not just speaking of climate change, here.
2. The scientific data is incorrect, and the problems are not real.
When a political ideology is in direct opposition to something such as regulation, you will typically find them to denounce scenario 1, and instead promote scenario 2, even using underhanded tactics to do so (see this thread:
https://bitcointalksearch.org/topic/dissecting-brownlashers-40283 ). However, data is independent of political beliefs. Given that, there is no correlation between what the science says and what your political ideology promotes. In other words, scenario 2 does not necessarily manifest itself because it is more convenient for those who believe in a certain political ideology.
You can argue that your political ideology addresses scenario 2 all you want, but that hardly demonstrates the robustness of your political ideology. To truly demonstrate the robustness of your political ideology, assume for argument's sake, that scenario 1 is correct, and then proceed to show how your political ideology addresses it.
Regarding what you might think as an edge case, and what I am quite certain is the fundamental foundation upon which mankind depends, bear in mind that there are complexities, synergies, and pathways that the average joe is not aware of, nor will he necessarily ever be aware of. We can be certain that 13,000 years ago, nobody would've necessarily been aware of any of those complexities, but the impact of 10,000 individuals on a continent is negligible, as compared to today's population, so one can argue that back then, knowledge wasn't necessary. Note however, that there is compelling evidence that those 10,000, actually initially estimated to be 300, did in fact have a drastic effect - it is called the overkill hypothesis, and I would be happy to debate you on that topic as well if you wish.
But back to the main point, and that is scenario 1. Are property rights, which are the premise of libertarians, robust enough to address scenario 1? Or is extensive regulation necessary?
