Hahaha, sadly that is not how it works.
That's not one of your democratic rules that you can apply willy nilly.
Democracy follows popular opinion, and if a popular opinion is that Alcohol is legal, gambling is legal, Islam is still not suppose to bent to it.
This issue on the other hand is much more personal and depends on several factors. Women are human beings and should not be treated as assets.
Imam Abu Hanifa (RA) was blessed with vision.
What happens if a wali is drug addict, abusive, exploiter and all that?
Basically, the issue is that Men want to control their women (daughters, wives, and sisters), even when they want to do something Halal.
That is how actually women like Marvi Sarmad and Asma Jahangir exploit the women in our society and take them away from religion, by showing the controlling nature of men. The end result is that women become feminists and think all men are hypocrites.
