> Additionally, just over 1% of adult U.S. citizens do not have any form of government-issued photo identification, which amounts to nearly 2.6 million people.
The rest of the statistic is about driver's licenses specifically, including technicalities like expiration dates and address changes. The online ID check for age verification don't care about the address part anyway, in my experience.
If someone has an expired drivers' license or they changed their name and haven't updated their IDs, they have bigger problems than age-verifying their Discord accounts.
