In even simpler terms it's the current "shut the kids up" tax that parents pay.

It's not to shut the kids up, it's to shut them in so that all the Karens that rat your ass out the minute your kid is spotted outside on their own won't be able to kick off an investigation based on a phone call that it's illegal for you to even see the complainant of in the report.

Society basically expects you to hide your kids if you can't watch them every second, the externality society imposes on parents is the costs of boarding them up inside.
