The obsession with helmets in many countries is born of an idea that violence on the roads is inevitable. It's a bit like responding to knife or gun crime by saying everyone should wear kevlar vests, problem solved! Rather than insisting that knives and guns are not used in public spaces.
Some people have real problems grasping this. Cars are seen as inherently dangerous, pedestrians and everyone else should (ideally) stay off the roads, and nobody should challenge our "right" to drive where and when we like. But driving is still a choice, albeit coerced since there are so few alternatives, and that choice has profound implications for others. Why should I wear protective clothing because you choose to drive a vehicle which puts me in danger? In the Netherlands, to respond to your point, they have largely eliminated motoring-related danger for cyclists.
If anyone is interested in the development of Dutch cycling infrastructure, this is an excellent video:
