Dakiras: Wouldn't that be nice, if such a thing solves all the problems; however, it wouldn't.   The age of a person doesn't define their level of maturity in the same way that on occasion someone who is over 18 can sometimes act immaturely, while others under the age of 18 may act in a very mature manner.   Such a restriction would not be the solution.
