When you fuck up in health, people can die. Regulation exists for a reason.
A lot of the regulation has allowed people to die when there was a chance they would have lived without it. Regulations on advertising and OTC drugs are absolutely needed, but stopping a doctor from prescribing a risky drug to a terminally ill patient who will die without it anyway is counterproductive. The main reason people aren't healthy has nothing to do with the medical system or regulation. It has everything to…
And if the patient survives, but has a debilitating condition that was a side-effect of that risky drug, then claims he was going to survive anyway and now his life has a shattered quality because the doctor prescribed an drug that hadn't been fully cleared yet? It's not as black and white as you're painting it, and drugs are not always silver bullets that save your life and send you back to playing the violin like the virtuoso you once were.
Conversely, if you didn't have that regulation, you'd have medication with a much lower quality - more people dying, and more negative side-effects for the ones who survived. Plenty of drugs look promising at the outset, then turn out to have serious issues.
