One other aspect is the obligation we have to others who we injure through our negligence. Law suit or not, if you damage the property or person of another through negligence, and you owed a duty to that person (you may even owe a duty to trespassers), the moral thing to do is repair the damage or pay for the injury and any resulting diminished incapacity. Mostly these obligations come from English common law and may have been expanded by American case law. Why do you think states all have "Financial Responsibility" laws for auto insurance? We all have an obligation to others to be responsible for our actions rather than find underhanded ways to protect assets and avoid our obligations.
