Any time law-makers claim that a law is meant to protect children you can guarantee that the safety of children had almost nothing to do with it. This is all a push to normalize digital ID (to protect the children!); once normalized it will become mandatory.

I always ask myself who wins with these laws (well, any law really). so far, the only winner seems to be the government and data collectors. It seems these laws are intended to collect leverage in the long run.
