One cannot ban these as there is a ncessity for the coaching class. If it is banned it will be continued wit hnew name for it because it is the need of the hour for the people.
Here is the big problem fo govt. If something is to be banned Govt should see whether it can be successfully banned or not , whether it is really required and what way the licenses can be given to run the classes etc. Blindly banning will not help. Better give licenses to run classes and tax the income earned. Those who wish to avail it will go for it.
