Banning computers in school wholesale is about as retarded as a fucking take as you can physically get.
That's basically the equivalent of saying we can't fix stupid so we might as well just kill every stupid person. It's just the most extreme fix to a problem that just creates more problems and hurts the victim even more.
At most I could see an argument saying that computers have to be stupid like they were in the 90s. Anything that says on you more than win98 shouldn't be allowed. But computer skills are an absolutely mandatory skill set.
