That isn’t sufficient for the people trying to pass these laws. They’re trying to get the government to enforce parental controls, not the parents. Those types of controls already essentially exist and yet they were deemed insufficient.
This is mostly because these people are not interested in protecting children, but rather shutting down anything they don’t like. The same way they tried to shut down abortion clinics by attempting to hold them to full blown hospital building standards. It wasn’t because it was unsafe, it was a way to harass the clinics they disapproved of.
I was always so disappointed in the 90s to see ‘realistic’ looking graphics and then you play the game and realize it was just a point and click game
