There are a few options for age verification, but the one I like best is at the ISP/device level. You make the account at the ISP level have a flag for being a kid friendly service. You could also have the government establish simple tools for parents to install on their kids devices which would limit other apps and services, for example by blocking porn or violent age inappropriate content. You could even have it tie in with the age advice for film classification, though the current classification guidelines are pretty horrible. All of that could be handled by a very small government team and could be deliverable in 6 months.
These are active steps a parent can take to limit their child’s exposure to the internet and do not come with added cost to the parent. They would be just as available for someone who is poor as for someone who is rich. It would be possible to protect kids from many of the more dangerous aspects of the internet while also leaving unmanaged devices free and clear, preserving the good things about the open internet.
