Good idea, but would be next to impossible to define "junk food". Would have to be food that is considered addictive I would think also, which would also be tough. Even junk food has some nutritional value. We are getting into a tough topic, because who would have to oversee that? The government has enough to do already, and I suspect many ordinary folks would really take issue to the government deciding what we can eat. Short answer? No. We can educate kids on how to eat healthy and learn to make their own right choices.
