While I don't agree with nanny state regulating this, I don't think your comparison is valid. Fatty foods were a part of our diet and then the experts at time said they were unhealthy and provided evidence - still the burden of proof was on them. Children were (successfully) raised for generations without digital devices - you need to actually prove it's a benefit otherwise it's wise to avoid it just on being conservative.
