I think basic formal education should be the right of every child. Basic formal education helps the child fits into the society and its every parents duty to give this to their child. Its okay to have an informal education, but every child deserves the basic formal education to help them navigate in the society and also help them to communicate better amongst their peers. Formal education helps you in reasoning, how to behave and many more things, so denying a child this education is denying the child a lot of things that will really help the fit perfectly well in the society,  so I will always advocate for a basic formal education for every child.
