They're the most important thing, someone might get hit by a piece of falling debris from the space shuttle, it doesn't mean it's going to happen to anyone else though :lol:
The whole, and only point, of taking risk mitigation measures relies on assessing what the risk actually is and not someone's emotional response to a situation. In your case the risk was the same before and after you fell over and the outcome no more or no less likely. It's just human nature to react to things that are either close to us personally or well publicised and it's not a bad thing, it's just the information to make a reasoned assessment before an incident is out there and it's better to use it.
The trouble with anecdotes is sooner or later someone produces one they think in some way disproves some rule, you might have easily said that you slid half way down a mountain without a helmet or injury and that proved it wasn't required.
Otherwise, what does happen is that people fret about things that are entirely unlikely to occur ignoring things that can happen.
The reason people wear helmets when under supervision in activities like rock climbing is that the formal risk assessment makes it a simple decision. You have a situation where the likelihood of the event is low but not zero, the consequences are serious i.e. up to and including multiple fatalities and the mitigation doesn't compromise the activity. You might arrive at the same conclusion for snow sports but you measure those inputs by available data rather than personal anecdotes.
