Thanks, that was a useful insight.
Karachi can not be a state, it can be given under federal Govt,
Yes, you are right. Maybe it can be a city state sort of thing under Federal control, with a strong municipal corporation to oversee urban affairs.
we should've Karachi like (not in its current form) cities in each provinces like KPK/Baluchistan/Punjab/Gilgit,
Well, you have a point there of course. But Karachi has a manifest destiny of being the primary port city and financial capital city of Pakistan and by default attract the best talent of the entire country.
As far as Sindhi feudal lords are concerned, once Karachi is freed of the provincial yoke, they will be less dangerous to the city.
