Perhaps that's true if you believe that parents should be the only ones responsible for their children's fate, but that puts a lot of power in parents' hands and doesn't leave much with the kids themselves.
I think there's a middle ground between complete standardization and complete reliance on one or two individuals that prevents the worst outcomes, although it may also prevent some of the best possible outcomes. But generally getting input from a number of different sources is a good thing, and even if "authority" may not be great at comprehensive development of varied individuals, it can still set minimum standards and make sure the child isn't entirely subject to their parents' whims.
