You're talking about a US context though. (I can't comment on the Maxine Waters thing.)
UK doesn't have some centralized database of all citizens' details that I'm aware of... 👀 I mean, everyone has a birth certificate, I guess. (At least, they're supposed to.)
Otherwise, they technically don't exist lol. Over 80% of people have a passport. (Some people don't like to travel much lol.)
No one has an ID card because they simply don't exist and Brits don't believe in that kind of thing and have repeatedly rejected any attempts to introduce them, so good luck trying to introduce them (equals political S-word, along with defunding the NHS, which is sacred lol).
You can leave the house with nothing on you and it's none of anyone's business where you go. Unlike in some countries where you have to carry ID all the time in case the police stop you and ask for it. Brits historically have thoroughly rejected that kind of thing, and still do. (CCTV on every street is fine though lol.)
There are tax records. Health records. Electoral roll records. Immigration records. Driver's license records. Criminal records. And other things.
But no national centralized database of all UK citizens that I'm aware of. (Unless it's secret. 👀)
Also, at risk of repeating myself (but for the benefit of some US people online here), "libs" aren't a thing in the UK and that term is essentially meaningless to most British people and they probably wouldn't even understand what you meant by it unless you explained it. Or even most of the world outside the US. It's really a US thing.
The only "libs" you get in the UK are the Lib Dems (aka Liberal Democrats), who are a sort of centrist party that win national elections once in a blue supermoon; although they do tend to do pretty well in local council elections. And, historically, if you go back far enough, they (or their predecessors) actually did tend to win majorities in Parliament, actually.
Anyway, the meme posted above is 100% fake news made up by someone for a laugh/to push some agenda, and it actually blows my mind so many people seem to have just taken it at face value. If it's really this easy to deceive people online, maybe I should get in on it lol. But God forbid you listen to scientists. 🤭
