All these new technologies are being scared away or delayed which harms the whole of civilization. Even worse, the risk slaying laws waste needless Human Energy that would have been much more productive if put to other use. A nation cannot regulate itself into Liberty. Remember Reg, society gravitates towards wisdom, not ignorance. Society gravitates toward prosperity, not degeneration.
Laws based on the idea of risk is laws based on fantasy.
I am sure you can imagine any type of Risk and then look upon Regulation as a preventive mechanism. But since Mankind's imagination is unlimited, the risks imagined become unlimited. Thus, regulation ultimately becomes unlimited. You expressed fear of risk of poisoned food. I could give you examples of risks forever.
