I am perfectly capable of assessing for myself the risks of swimming across a small pond in Massachusetts, or the risks of swimming in the Amstel when lots of boat traffic is around. I don’t need regulations to protect me; I have common sense. What I can’t assess for myself is the risk that the water is contaminated by raw sewage. For that, I need a regulatory agency that stops households and businesses from polluting the river. To generalise: for risks I can assess myself, I don’t want regulations that prevent me from doing as I please just because I might end up suing the government. For risks I can’t assess myself, I do want regulations that give me the confidence to do as I please.
