Steelmanning the opposing position: one adult shares their certificate with every child on the planet.
Because it has no attributes (not even a unique serial number that could be used to track it) the whole scheme is now defeated.
Which, adult is merely someone who's just turned 18. What're the chances that any of them just post the thing up on 4chan? (I'm going to go with 100% chance of that happening.)
