Well, you can't.
Like no past generation could stop their kids.
With all due respect.... this younger generation (zoomers and "alpha") is on average utterly clueless when it comes to technology.
Fluent in pod tide trends and latest sticker packs, but utterly unable to comprehend anything not working, be it wifi, proxy, dns, their phone's mobile connection. Unable to even ask the question "_why_ is something not working" or "what can I possibly do with this arcane message obscuring my $app's screen".
I know that's a quite broad generalisation but I see this in my kids' school across basically all their peers, and I can observe it online.
Anything broken -> passive hang up until fixed (of course if they cna talk to their bestie about the issue, this is what they do).
Just like no past generation had so much information so readily available. One quick quip can always be rebutted by another quick quip, but it doesn't really move the conversation along in any meaningful manner.

Past generations absolutely protected their kids from cigarettes and alcohol. A gate doesn’t have to be 100% effective to have net benefits.
