No, you misunderstand.

You're reaching for legally mandated solutions. Why can't this be one?

"Choose to be a good parent, vs legally mandated spyware". Why not "legality mandated be a good parent"? This would solve a lot of other problems too. Like, all those people who hand wring "oh we've tried nothing and we're all out of ideas! It's not working! Whatever could work in aggregate?!" people who don't actually parent can be trained to parent, and if they refuse they face consequences.
