Trying to tell people what exactly they can or can not wear is objectively bad, this should be pretty clear. If women's liberation is the goal (which most countries who have banned it have claimed), the more appropriate response would be work towards removing the social hierarchies that tend to place men above women (whether it be through improving access to healthcare for women, abolishing the systems which tend to make women reliant on men in capitalist systems, etc). If these things are achieved, then women who don't want to wear it won't feel forced to by their society, and those that do wish to wear it can do so freely. Banning the burqa is really just racist governments being racist, with a facade of caring about women to deflect backlash.
