On a very simplistic level it does seem like a good idea. Take everyone's DNA at birth, check if they're prone to any sorts of illnesses, take preventative measures or use it to track down criminals.

However, on a day to day basis there are too many variables about it - like the insurance risks and the risk of getting the wrong person for a crime. The trouble is as well that it won't take long before DNA is said to be 100% perfect way so that no one will have any recourse if they believe that DNA has been wrong. Haven't there already been cases when men have been identified as being a father of a child and they dispute it and it's proven that the DNA testing was inconclusive or the other way around.
