Some important context here is that Switzerland already has a national ID card system, this is an extension allowing people to use a digital version if they prefer.
I’m not saying that isn’t going to be without its privacy concerns, but them narrowly voting that in is a far cry from, oh I don’t know, the UK government forcing an entirely new scheme on people without a referendum.
Yes, if the government was sane and allowed a physical card as an alternative/backup, but the UK gov wants to make it digital only.
