Um, how the hell did you get from what I said to what you said? I was, and am, advocating drugs that have a definite positive affect, without side effects that are too bad. That's basically what the FDA is looking for when they allow a drug onto the market.
I also fail to see the magical thinking. If the FDA requires evidence of safety and effectiveness before putting a drug on the market, then a drug on the market can be expected to be actually useful, without any consequences too dire (or the FDA will rescind its approval). What this has something to do with a guy named Knut who wanted to show he wasn't all-powerful escapes me.
Pharmaceutical companies concentrate on drugs they can legally sell, for some odd reason related to making money or something. If they're prevented from selling useless drugs, they'll try to make useful ones. They don't develop drugs at random, you know.
