Because these are ultimately excuses for spying on adults

Perhaps a better implementation of the law would be requiring all sites to mark content as NSFW if it is, and having opt-in device level toggles, so parents could protect their kids more easily, but anyone who’s actively seeking the content is able to. Teenagers will get around this ridiculous verification with ease either way.
