You could always have the magic mirrors not be in a closed system; the more the Smurfs share, the more an outsider can see what they share, harvest it if you will, and sell it to third parties who may or may not want to cause disruption in Smurf Village or sway their opinion on important matters. The Smurfs would of course be blissfully unaware of this until someone alterts them to the leaks. It would be totally fantastical and not based on anything in real life. ;)
