Unnecessary rules will suppress people. Young Afghans are having some freedoms for the first time, and they don't know ways to maintain them and gain further freedoms, unless they are provided with a situation and are encouraged to obtain more freedoms.
Any unnecessary restriction might discourage them and they will lose their confidence and will never try new things. There are a lot of things young people in the west would do that afghan youths can't and it's because they don't have the confidence. When you come to rules and regulation it's not important to have it and implemented because it has traditionally been done so, but it should be put in place if it's required.
