You are the person requesting others comply (on behalf of the aggregate) the onus is on you to provide this solution. The solution that was provided, specifically engaged parenting, is the appropriate response.
Nope, because it will be passed unless you come to the negotiating table in good faith. The truth is that all this resistance mean you don't get a seat at the table, will be left out of discussions and your worst fears will come to pass because you took a hard-line position.
Good luck. People who aren't willing to collaborate don't get what they want.
Now that we've gotten the ad homs out of our system, provide a solution.
I'd like the nice thing of a workable solution. The failure to do so means you get the first proposed solution - the one you obviously don't want. It's crazy to believe that despite detesting age verification, none of that vitriol can be redirected in to coming up with a workable better idea.
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.
