Re: They should have
I imagine the elderly black folk suddenly evicted from Britain after 40 years because "hostile environment" polled well with Telegraph readers might take a different view on whether lack of an ID card is a good thing.
Same for the folk who will be turned away from polling booths in the upcoming local elections for not having any, or who are eyed suspiciously by landlords because they talk a bit funny or look just a bit too dusky for comfort.
The rest of Europe manages quite well with ID cards and tends to sit politically to the left of the UK. So it's all well and good banging on about civil liberties, but it seems to me that the lack of an ID card is also quite effective at disenfranchising Britons. A voluntary one would probably solve more problems than it causes.
