If you want “papers, please” every time you back out of your driveway or go beyond your government-assigned oblast, then your suggestion is the digital version of the physical authoritarian nightmare that was imposed by totalitarianist regimes throughout history.
People have a right to complete anonymity, and should be able to go across the majority of the Internet just as they can go across most of the country.
That’s what you are missing.
Don’t get me wrong, I am also in favour of a single government ID, but in terms of combatting identity fraud, accessing public resources like single-payer healthcare, and making it easier for a person to prove their identity to authorities or employers.
It should not be used as a pass card for fundamental rights that normally would have zero government involvement.
>>> People have a right to complete anonymity
Why? (Am not trolling. Genuinely interested)
I walk out my front door in the UK and I am not anonymous. Every transaction I make either identifies me through bank, railway or other id, or quite simply by my face standing in front of the coffee seller. My walk down the road is observed by neighbours and postmen.
Should my government arrest me without cause or trample on my free speech rights, I get that’s a problem but I am not sure why being anonymous helps. Having rights upheld by the courts helps, well trained police who respect the law helps.
I am honestly open to debate on this but I do find the “what if Hitler took over government where would we be” to be a problematic argument not a final answer.
