Why not? For the same reason that you don't have to take a test or "have training" before having children.
Yea, it's a good idea and yea, you SHOULD have to prove you have the knowledge and resources to properly raise a child before having them. But, it's your god given right to screw up (raise) a child any way you see fit and any talk of requiring "training" or being judged "competent" would be an infringement of your rights, right?
