I don’t agree. It’s still ultimately up to the parent to keep an eye on what their kids are up to, talk to them and prepare them to handle ugly things (which they will encounter at some point whether you prepare them for it or not, no matter how hard you try to keep them in a bubble), and if they feel necessary impose restrictions on a household basis.

Even if I did agree, the implementations being rolled out present far more danger to adults than requiring an ID to enter a physical establishment ever could. Internet ID systems are rife for political abuse for example, and requiring age attestation at the OS level endangers general purpose computing, adds yet more hoops for free open source OS projects to jump through, and risks making FOSS OSes illegal to use for those who need an escape hatch from their commercial counterparts the most.
