I'm all for systemic changes, but lets make them more real than a national firewall, which is only treating a symptom, and instead focus on how we can make raising kids economically and socially feasible again.
I never said we should "push" responsibility on "every single person that interacts with kids," however, it wouldn't hurt if families would actually "take" a little responsibility in it. If we had UBI it would be a lot simpler for them to do so, but I'm guessing that's not on many peoples' list of systemic changes.
