Malaysian Travel Restrictions

Malaysia has decided that women can't be trusted to travel abroad on their own. They should get written permission from their families or employers. Supposedly, this is because single women are being used by gangs to smuggle drugs. What I want to know is, how would a permission slip stop this? They seem to think that if the family agrees to a trip and gives a woman written permission, then somehow she's not involved with drug smuggling. What?!? So if a women is pretending to go abroad for a conference, now all she has to do is tell her family that and get a permission slip signed. And she can still smuggle drugs. I really do wonder if this is for real, or if it's an attempt to restrict female travel and they needed some kind of excuse for it.
