Why do we have government incentives?

In yesterday's NST, there was an article about scrapping the "lucky draw" for remaining folks who haven't converted to MyKAD (here) . I fully support the government's efforts to do this, but question why they had to do this in the first place. Isn't a fine and threat for a jail term enough to "encourage" these stragglers to convert? I work 40+ hours a week, and spend a lot of time with my family of three after that, yet I am able to go to the registration department and get both mine and my wife's myKAD done (yes, we got it done before the deadline). C'mon lah, it's not as if it takes 6+ months like five years ago to get a replacement card.

It's like the JPJ and PDRM giving 50% discounts to people who haven't paid their summonses. What next - 50% discount on jail term for murders and rapes if the suspect who is in hiding, or 70% discount on your mandatory death sentence by hanging for repeat drug users/sellers?
