Another part of the law (I honestly don't know if it has finally been approved) would require that any software programmer should be registered to their local police headquarters.
I don't think so. I heard rumors, but couldn't find it in the law. There only is a registry for people that sells or produces audio and video material for profit. Disclaimer: I don't have the law with me right now.
Hm, you could use the law to show the absurdity. If ervery friend or relative of any hacker in Italy tries to register it would breake the system.
When there is such a registry, it is about people that produces <thing> for profit, so your idea is not applicable. Even if it was it wouldn't break anything. Neither politicians nor the police is impressed if people is spending hours in queues.
