à dont know why its much easier for you to serach for different reasons why muslim women wear hijab all over the world rather than accept our reason ´we muslim women´ ?! 
Actually you think through pink glasses here. The world is not as rosey as you see it! Muslim women have MANY different reasons to put on hijab and not all of them are as lucky as you are: you have the choice, and, more importantly, the brain to make a decent choice!
The reason I mentioned those ´highly educated women in Turkey´ that you were mentioning, was because I think that the situation of those wearing Türban, is very different from the things that were discussed here, so I thought you shoujld know the difference. Another reason is that I had a masterclass about this specific topic, so it happened to be something I researched about for unviersity, not just because I shut my eyes for it ´being a divine order´ and because I enjoy researching different reasons just to prove you wrong. Why is it so difficult for you to accept that not all women do it for allah like you do?
Women wear it every where at the world not just at some places so you can get a historical reason for that
Women wear it in German...in South Africa, in Australia, at Saudi Arabia, at Ãran, at Egypt, at Türkiye, even in China..etc
All those wear it would have a special reason for each country rather than the obvious one that we wear it because its an order from ALLAH ?! 
Let me tell you a story from my highschool. To give you some idea on wearing headscarf in the Netherlands: two of my classmates were forced by their families to put on headscarf. One of the girls was Turkish, one of the girls was from Marocco. They came to school half an hour early everyday. In the toilets they took off their headscarf, made their hair and put on make up. They went home half an hour late everyday, cleaning their make up and putting back on their scarf. This is just a small example: 2 girls on a highschool in a very small town in the Netherlands where not that many foreigners live. I cannot even think about the bigger cities in the Netherlands, where there are more foreigners than Dutch people (though I consider them dutch as well
). And you are telling me that some women do not have a special reason in each country for wearing it? For you it is an order from Allah, for them it was an order from their family and they knew they would be beaten up by their brothers if they would ever take it off with their knowledge! For others its an order of their government (SA, Iran).
