If you're trying to make an analogy between mail and school, I think FedEx would be more equivalent to a private school than home schooling. And FedEx, much like private schools, has to to comply with a bunch of government regulation. In the case of FedEx, they have to check to see whether there are drugs or bombs in the packages. FedEx also has to deliver the package, you can sue them if they fail to perform their contractual obligations. Private schools have legal requirements and report evidence of child abuse and have to provide actual education. In this child = cardboard box analogy, I guess home-school would be equivalent to transporting the box in your own car. In this case, the box would also be subject to scrutiny, for example at border crossings.
