Decentralized social network Mastodon says it cannot comply with age verification laws, like in Mississippi and elsewhere, and says it's up to individual server owners to decide.
Making the certs short-lived (a few minutes) and single use and having a rate limit for users could make it difficult enough with serious risks (if you make it a crime) for little profit (I doubt many kids will pay serious amounts of money to watch porn; definetly not drug-scale amounts of money).

You cannot make a certificate “single use” (except if it exists only inside a closed system).
The website generates a random value, your government signs a cert for that value. That’s what makes it single use and zero trust.
