The proposed rollout of the so-called BritCard is a bait-and-switch psychological operation (psyop). The evident purpose is to frame the debate about digital ID in the UK by fundamentally misrepresenting (https://iaindavis.substack.com/p/uk-digital-id-the-britcard-bait-and) what digital ID is.
People often say “if you don’t have anything to hide what’s the problem?” There is no rational argument for allowing people you don’t know and have never met to have any power to control your life. The “nothing to hide” mantra is based on the historically illiterate assumption that you will never have anything to fear from authority.
