Don't try this at home

One school of thought says that we should make things safe so that people can do what comes naturally to them with no ill effect. 

I maintain that it's just not feasible to child-proof everything and at least some of the time it's better (or even necessary) to teach people to use good judgement and be cautious instead. Sometimes the correct answer is "don't do the thing" not "we'll make the thing safe".
