It's a nightmare world.
Follows directly from the extremely patriarchal reading of Islam the Taliban uses (borrowed from Salafism in Saudi Arabia initially). Every single thing that can be interpreted negatively for women is so interpreted, with no understanding of the change in eras and meanings.
For instance, in Afghanistan women's shoes are not allowed to make a noise. This is because during the era of the prophet prostitutes wore bells around their ankles.
The ban on women traveling alone beyond a certain distance is also related to that earlier time which was extremely warlike and where traveling alone for a woman would have been suicidally dangerous.
The assumption that nothing about women should be seen but their eyes, however, is more dependent on later interpretations which seemed to argued that it's impossible to know what the hadiths about female modesty actually mean so better be safe than sorry and so cover the women completely (because it was no inconvenience for the men and all the religious interpreting was done by them). Indeed, the Quran says that both sexes should dress modestly and not much more than that.
All this is Taliban: The Sequel, for the 1990s version of the same. And it's not a film, but a demonstration of how poorly women can be treated in this world.
