A phone isn't going to run off the road and kill 7 people. This is nonsense and you know it.
And yes, phones are something parents do "just" share with their kids because nobody is bizarre enough to look at a phone the same way as a gun or a car. It's the YouTube device that can talk to grandma. All you have to do to see proof that it's something people "just" share is to walk into a grocery store and look at parents pushing kids in carts while those kids watch videos. 25 years ago those phones were Game Boys. Nobody is seeing them as a gun. That's the most disconnected from reality take I've seen in my life.
Whats the diff between today giving you phone to your 8-year and making sure /having trust that they do not use it to e.g. order a new toy from Amazon and tomorrow that he is not using to verify they are an adult? I mean, most things today (like accessing porn, buying alcohol) do not require any extra age verification. They can just do it using your phone/accounts.
Not everyone views their child as an enemy that just happens to be in close quarters with them. Most people trust their kids to generally not do bad things. People keep knives in their kitchen and kids, explain the danger, and kids are generally responsible enough to not play with them.
If this is a concept that you can't grasp, then words will never convey it. It's simply a detachment from reality to think people are viewing their phones as a loaded gun and their child as someone hellbent on betraying them and causing massive societal damage.
The phone is the YouTube device. If they get a notification that their kid ordered from Amazon, they'll cancel the order and tell their kid not to do it again. It's seriously that simple. Just go and talk to a parent. They'll think viewing their phones as a WMD is insane.

Okay, so trust them not to access age-gated sites using your credentials then.
Then just get rid of the age gating and verification entirely because it's useless.
Other parents have different opinions to you about the value of this.
