Mass surveillance is far more damaging. Also there are several porn block solutions on offer for parents to install on their children's devices. There is absolutely zero need for the government to be regulating mass surveillance on everyone to block porn for children. We are replacing the damage caused by porn on a small handful of people who are predisposed to get addicted and got exposed to it at a young age due to bad parenting, with damaging all of society with mass surveillance, which is not even guaranteed to stop kids from seeing porn.
