This is exactly the issue that drives folks from "bad schools." The inability of those schools to control disruptive students.

If public schools were permitted to prevent the harms of disruptive students from impacting classroom management by informing parents, "You child is no longer welcome in our classroom, you are required to find someone who will put up with them" and handing them a voucher; then I strongly suspect we would learn that the quality increased and the number of disruptive students went down as parents were forced to deal with the costs those students had imposed on us.
