You can trust that the government wants to protect the children. The question is what does "protect" really mean. Western governments do a pretty good job of protecting kids from labour exploitation, for example. But that's because it's relatively easy to enforce. Protecting them from other harms is more difficult and involves tradeoffs with personal or parental freedoms. I really don't think these initiatives are intentional power grabs... although you're correct that opportunist entitites will exploit these regulations to empower themselves.
