This is just the latest in a long trend of increasing spying on users. Why bother having to guess who your user is, or fingerprint a browser if you can just force them to show you their national ID?

This is transparently about spying on people, not "protecting children". The real world doesn't require you to show your ID to every business you frequent, or every advertiser you walk by. Someone can yell a swear word on the sidewalk, and not everyone within ear shot has to show ID.
