That's already the case. Since you must be able to identify yourself when asked, you have an obligation to carry your identification with you.

I believe the obligation to carry identification, and to have identification are enforced differently in different countries / states. But there is more information here:

> At some point there will be a situation where you cannot do anything because you are in the 0.01% of the system that is broken.

Not wanting to identify yourself and not being able to identify yourself are two seperate topics. I sympathise with people who fall outside of the system, but e-identity is currently a matter of convenience for people who already have identity documents and are seeking easier ways of accessing services online.

The UK is not a part of the EU any longer, for pretty much all of the rest member states, that has not been an issue for quite some time... save for Ireland.

The issued ID plastic cards would be as useful when you are present in person.
