Personally, I have no issues with schools being closed and never having physical locations again. It works fine for a lot of families. It gives them the opportunity for more supervision of their own children and less influence of the mob and culture at large. Perhaps the best thing is that it really drives home the importance of public schools and public school teachers. If they are not careful a lot of these parents will suddenly realize that they can do this education thing for their kids on their own and that grade school teachers are by and large unneeded. Destroying teachers' unions naturally through attrition can only benefit society.
