high security car number plates

high security car number plates why is government so keen on high security plates for all cars? how will it make car theft difficult? the thief may not be able to sell the car as such but it can always be dismantled and the parts sold off. will it make any difference in committing a crime with a stolen car? it is a car plate, not a camera which will record the face and movement of the criminal. how does it matter if i expose my car to danger of theft. it is my car. after all i smoke knowing full well that it may cause cancer. the government does not stop cultivation of tobacco for that reason. it is all a misplaced concept of welfare. why have i to be helped to cross the road even if i do not need any help?
