Hah this is the UK. No, it'll be optional to begin with to make people like you asking important questions seem like a whacko. Then once they use propaganda to make people opt into it, and it reaches mass adoption, then it'll quietly be made mandatory - or extremely annoying not to have it
Yep. It's literally always this way. It's starts with "we hope everyone will do the right thing". To, "it's concerning some people are refusing to do their part". To finally, "do it now or we'll lock you in a cage".
