Citizen Lambda has a salary, all the cards, keeps working doesn't earn a huge lot.

Citizen Gamma had a great job, stopped working, smartly invested his money and doesn't have cards but a lot of cash.

Gamma wants to get gas at 2 AM; the only way is with a bank card 'cause there's nobody at the gas station to serve him.

Gamma wants to travel abroad, needs a rented car there and to reserve hotel rooms. He doesn't have a Visa card. How does he do it?

Lambda knows he has nothing to hide 'cause everything he does is traceable. So he leads his life without worrying getting cought while Gamma knows he's going to have the visit of a tax inspector and takes all the measures possible not to leave any trace (and can't show a lifestyle way outside what he will have to demonstrate to that inspector).

Who's the one with most freedom? The relaxed or the anxious?

Suppose governments were able to restrict your freedom with the help of our cards. First, there are consumers and human rights organizations to protect citizens, then, above all, elections. Why would a democratically elected government act against its citizen's interests?

But anyway, ID cards cannot be used to trace how you're spending money and what you do? Other cards do that. And my first post was about the value of the identity card.
