I've seen the FDA pull everything that works off the shelf. I'd rather see them lined up against a wall and shot than be allowed to continue operating. Snake oil salesmen never did as much harm as they have.

Obviously having it work well would be better than either extreme. Regulatory agencies all bypass Constitutional separation of powers, and they all cause problems for that reason. No other has directly impacted life and death, or quality of life, nearly so much that I'm aware of.
