You might be surprised - I'm very much in favour of letting competent adults make informed risk decisions, and I'd much rather concentrate on improving the quality of information available to them than on restricting their choices.

Problem is, even if RL had a few House-level medical geniuses around, it's not practical to say "ignore the rules if you're a genius". People just aren't that good at self-evaluation. So we end up with a tradeoff between letting a handful of geniuses save a handful of people by breaking the rules, or letting a truckload of overinflated 'geniuses' kill people through whatever brand of quackery they firmly believe in.
