I don’t get it. What is to prevent a 9 year-old from buying a certificate and using it?

This video addresses that:

All certificates are cryptographically linked to an identity-anchor certificate, meaning buying a certificate would require the seller reveal the private key tied to the identity-anchor certificate, a tall order I would argue.

In the case of stolen identity certificates, they can be revoked thus making their illegitimate utility limited.

So an older brother gives his sibling a key.

Why would your design prevent that?

We can still have laws, e.g. that using someone else's certificate (or knowingly giving them your certificate) would constitute fraud.

We have laws against kids buying alcohol, even though kids can (and do) try to get adults to buy them booze, but I don't think that's a good reason to say we shouldn't have laws against kids drinking.

		Sure, I agree. But we're talking about a claim by GP that his cyrpographic system prevents this behavior. If it can't, it's no better than a button that says "I'm 18"
