None of this is for what you're describing though, there is no reality where such wildly different countries and states in different corners of the world all decided coincidentally to all do this within 6 months of each other. We know it's not "well maybe they saw X country and thought it was a good idea" because even percolating the policy would have taken over a year.

Protecting kids is just the PR reason, the real goal is requiring ID auth for every action taken on a computer. If we normalize it for downloading apps or using websites the next step is to authorize it for connecting to HTTPS at all and then the next step is requiring it to unlock your CPU cores.

If people don't push back on this now there is no world where we get out of 2030 without requiring government ID auth to install linux on your own computer not connected to the internet.

End to end silicon to server auth is absolutely possible and someone is working really hard to make it a reality.
