I’ve lived in a country where we had ID cards and yes have been asked to produce it by police (random check) can’t say it bothered me, I found it useful on many occasions. I am in favour of ID cards on the whole, anyone who thinks they can live totally privately obviously never uses any public health, education , pensions, benefits, never travels or uses any social media. There’s lots of info out there on us and an ID card would bring lots of public services together more efficiently. It could prove citizenship, avoiding such scandals as Windrush, since the data could be used to control and confirm immigration and citizenship, prove entitlement to vote, use health services, useful in employment, maybe even give some sense of national cohesion. It could also save money in avoiding duplication of so many different ID forms. States such as South Korea and a Taiwan tacked the Corona Virus much more efficiently as they had more detailed data set on its citizens in terms of health records and travel history. We tried a one off track n trace app , but a national identity system would have made this unnecessary, more efficient, and could have saved £billions (and lives). This data would be of course fully accountable to the public. It could help prevent voter fraud and identity theft. Social media has meant there’s loads of data out there without any accountability. Any notions of total privacy have been broken down somewhat in the digital age. Yes, you could easily forge a card, but you can’t so easily forge the data behind it . The main argument I can think of against it is that this government is so inefficient they are bound to bugger it up, but one reason they are so inefficient is that the right hand doesn’t know what the left hand is doing, some unifying mechanism would improve this. If other countries can do it and save money and be more efficient at the same time , it can be done without anyone loosing any notional freedoms.
