I would postulate it's because people feel uncomfortable in situations where they are made to feel like lab rats, and that as a society we decided that these rules should be in place so that people who do not have the same views do not abuse those of us who do.

Such experiments are run all the time on large populations. So that's nothing new. It's interesting to see what views there will be about this time after decades. X-ray show fitting matchines? Radiation pills to cure everything? Will aspartamine be allowed in food products after 50 years? Will it be allowed only because it was allowed earlier, even if it's known (then) to be dangerous? What about mobile phones and radiation? Is it ok to have 2w microwave trasmitter attached to your head all day long? Etc. Why is alcohol and nicotine still allowed to be sold, even if known to be toxic and damaging to health. What about acetylsalicylic acid as analgesic, and list goes on. Margarines were really popular at one time, and adverticed as healtyh option to butter.
