It really depends on the "use case." Regulators are primarily concerned about grooming, which involves criminals using apps that teenagers frequent.
Also, criminals usually have poor operational security—far from perfect. The seriousness of the offense isn't related to the quality of their opsec.
Regulators and law enforcement are generally rational. They may be short-sighted, but they often have reasonable explanations for things you might dismiss as stupid.
That sucks, CSAM sucks, emotional regulation sucks, and as a society, we don't know how to manage allowing kids online. In fact we don't even know, what we'd like. From a political/policy standpoint, that's the challenge of the next 20 years.
That's trying to find a technical solution to a problem that is not technical.
The sad truth is that law enforcement doesn't have the resources to go after a huge chunk of the cases - particularly before anything serious happens.
For this reason giving them even more power won't markedly increase prevention, but will introduce more cases of people abusing said power. Ultimately the government is run by people, and people are fallible:
And if you tell people that quitting smoking, drinking, and walking 10,000 steps a day would make them healthier, that’s true, but it’s not helpful on a national scale—especially for issues where the cost is not only borne by the individual but also by the rest of society.
This works - until they grow up. Will you filter the world for them when they are adults too? Your role, as a parent, is to prepare them for independent life, life without you. How will you do that if you never give them the reins?
