The libertarians I know are against regulation. Instead you are supposed to sue the party that has injured you. Good luck proving that you were injured for example by leaded gas. It's hard enough for a government agency with many lawyers and scientists to prove long term harm done by pollution. As the little guy you have no chance against a company with deep pockets who can buy as many expert witnesses and lawyers as needed.
