Even worse than this. What if the government suddenly makes abortions illegal, or use it to round up LBGTQ people, or people with immigration status’s that aren’t standard. Even without going USA dystopian, a person under the age of 18 that is abused by a caregiver and needs to privately visit websites that would give help and advice. The use of the rule to limit free speech and the inability for small websites and groups to not be able to manage the technical ramifications of stopping actual 18+ content, so just put up an age restriction to protect themselves means lots of free resources with no actual 18+ content are being shuttered.

And yet a child can still easily get to 18+ content and content of harm through Nintendo chat or their text messages and chat with others.

It’s a bit like when a games manufacturer makes your new game you purchase have to be connected to the internet so they know you are not cheating or stealing their game. It adds barriers for legitimate users and purchasers yet people pirating or cheating have ways to get around it and actually have a better game experience than those that are playing by the rules.
