The government is not the answer in any case except what the government is granted in the Constitution.
Actually, our Constitution charges the government with protecting its citizens.
The government is already far to involved with every aspect of our lives, and need to get out of most of it.
In a fantasy world where every person on the planet is respectful, fair, and considerate of everyone else, we wouldn't need a single law. However, in reality, it seems that damn near everyone is constantly trying to steal, rob, shaft, burn, coerce, manipulate, screw, injure, or kill everybody else. And those who are not doing so intentionally, are doing it through incompetance, irresponsibility, immaturity, or just a simple lack of common sense. Either way, something has to be done to try to protect society from those who would do us wrong, either intentionally or unintentionally. Hence, our ever-increasing number of laws.
If you have a better way, we're all ears!
