Reminds me of this:

"So here I was now, two years just to the day of being kicked and clanged into Staja 84F, dressed in the height of prison fashion, which was a one-piece suit of a very filthy like cal colour, and the number sewn on the groody part just above the old tick-tocker and on the back as well, so that going and coming I was 6655321 and not your little droog Alex not no longer."

Nothing like a little bit indirection to make it not true. It's blatantly obvious all the ways G can build a profile of someone by fingerprinting. Unfortunately it's not exactly an elevator pitch to make it a common knowledge thing.

“I am not a number! I am a free man!”

I don't think this would stand up to scrutiny if the EU was willing to really enforce the GDPR (unfortunately they are not).
