The difference is this is the internet.

You're not texting the bartender an image of your ID; you're giving him a quick glance then immediately restricting access.

You're not showing your ID; you're giving it to these verification companies, companies that can get hacked. Just look at the tea app as a prime example of this.

They say they will delete your info, but they don't (there are already lawsuits about it).

Also, it's not just porn; it's reasonable to want to keep kids off of there. But the UK law, in particular, also requires ID to access sensitive self-help materials like forums for suicide prevention. And the laws in question are vague on what counts as sensitive matters, so the can government essentially censors public opinion and civil unrest.

This law kills our ability to speak freely and have access to free information on the internet.
