Well, my general approach is to think that we should continue political discussions as long as they are not indicating mind-killing. For example, I find your point about liability insurance to be very interesting, and not one I had thought about before. It is certainly worth thinking about, but even then, that's a different type of regulation, not a lack of regulation as a whole.
Some libertarians oppose limited liability for shareholders of corporations because it distorts the incentives to reduce the risk of harm to third parties. I tend to lean in that direction although I can see the merit in some arguments in favour of limited liability.
To whom it may concern:
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
