Concretely, if the high school has 1000 kids, you need to block the 99.9th percentile teenager. That kid’ll be a local legend if they’re the only one to figure out the bypass, and they’ll share it with friends.
(It’s actually harder than that, since kids in different high schools communicate with each other.)
We could just sequester every teen into a sound proof cell, hand them a bible for all of their educational needs, and finally dump them out into the real world the day they turn 18.
Don't need the average kid to be able to, you just need the average kid to have access to a peer who can do so for them. Which is quite reasonable.
