The problem is they're trying to implement a law that was put in place to stop kids buying alcohol to stop people looking at pornography. It doesn't translate well into the virtual realm.

Circumventing the checks isn't illegal because they don't want to be arresting a bunch of kids. So they just take the fake ID or whatever off them. They haven't bought any alcohol, because they were found out, so no crime has been committed. The law makes no allowances for adults buying alcohol legitimately but still bypassing the safety checks because no one assumed that would happen, and where you're just handing over your driving licence to a store clerk it wouldn't.

But we're being asked to trust third-party companies who routinely lie about their cyber security. Now there absolutely is a reason for adults to want to bypass the checks even though they're overage.
