Technically I'm not in favor of limiting rights or imposing dresscodes but certain limits should be set, you can't walk around naked and imho you shulnd't be allowed to walk around in a burka, its two sides of the same coin, extremes, extreme religiosity is not good and the state should limit it, even by limiting niqab. sure a ban would confine a couple of women into their houses but it may also detter other from wearing it, creating the room for a more moderate Islam as the article states. It could have an adverse effect though, Muslims may view it as another form of repression.
