Or perhaps because women who have wanted to work in health or flight have been historically relegated to secondary roles.
Even with a cursory Google search you could read up and inform yourself about actual examples and why anti-discrimination laws we created (from 1971 no less!): http://scholarship.law.berkeley.edu/cgi/viewcontent.cgi?article=2664&context=californialawreview
The fact is, as you've pointed out, that people naturally have different preferences. However, those preferences are at the same time shaped by one's cultural surrounding -- nature versus nurture. If one's culture explicitly discriminates who can do what based on traits that are unrelated to natural preference and competence, then the participation rates you claim to be evidence of preference are fundamentally unnatural.
This is not hard to understand.
Many people do in fact experience such discrimination. The effect of this discrimination is unknown, but that is the whole point of being open to understanding these issues. While there is no such thing as solving discrimination (because of the imperfect nature of humans), investigating these issues may in fact lead to better matching of individuals to productive and preferred roles in society.
That would be a net gain for society.
