In the modern era of more and more families having only one child, I don't think replacing school by online learning at home is a good idea. Children need to be exposed to other children, kids with diverse backgrounds if possible. Also, there is a time to be free and focus exclusively on what you like, but I'd rather have kids exposed to a variety of disciplines first. Perhaps more importantly, I would not trust most parents to provide a good learning environment to their children, especially in poor families. And online learning might be the most efficient for some students but I expect that other students benefit a lot from the personal contact with a teacher. Ideally we should be able to give each student what works best for her.
