Several of these involve housing. IMO it makes sense to regulate safety in the housing market because the housing market is broken - I would not be surprised if at least in some cities, complete knowledge of the consequences of asbestos in the walls wasn't a deterrent even if the renter was fully rational. With those that don't, I think full information and personal responsibility is still the best approach. Do you want the cancer creme or the non-cancer creme? That said, I think we would get most of the benefit of regulation if we just required an advisory consultation with your GP before you could buy a product whose safety wasn't established. A lot of the danger of overregulation rests on trivial inconvenience vs outlawing experimentation, and I think something like that could split both groups. "Yes, I want to enable experimental mode on my body."
