Note the "or"

Multiple platforms have had that an an option. It's really odd as a concept to me, does it only work for very obvious cases and for people around 18-30 ask for an ID anyways?

You do not have 'civil liberties' in the UK. There is no Miranda rights and there bill of rights is strictly based on the Magna Carta and is not as comprehensive and the US Bill of Rights which was based off of the UK version.

Per the wiki:

Civil liberties have been gradually declining in the United Kingdom since the late 20th century. Their removal has been generally justified by appeals to public safety and National Security and hastened on by crises such as the September 11 attacks, the 7/7 bombings and the 2020 COVID-19 pandemic.[4][5][6] The pandemic oversaw the introduction of the Coronavirus Act 2020, which was described by former Justice of the Supreme Court Lord Sumption as "the greatest invasion of personal liberty in [the UK's] history."

Enforcement occurs at the application level. You can think of applications as analogous to search engines. They're aggregating view layers (which is why they're called AppViews). They are largely where moderation or regulatory requirements are enforced.
