> Compared to the UK where you need to have some utility bills or bank statements as proof of an address, having an ID card with an address is a lot easier in practice.

Well, no.

You already have bills in your name, so there is nothing to do.

On the other hand, regarding ID cards (in France): First there is no obligation to keep the address on it up-to-date (so why is there even an address on it?). Second, if you do want the address to be up-to-date then you need to follow the administrative procedure to get a new ID card, which involves providing... a proof of address in the form of an utility bill!

So France is different from Germany where you can get the address updated and you are supposed to do that. And proof of address is not a utility bill there, but either a form from your landlord or land register.

Same conclusion: You still have bills, tax bills, etc, so there is still no need for anything else if you wanted to keep things as simple as necessary.

Because you've decided to do that, not because there is a practical requirement, which is my point.

Not really, as you still need to show a passport that you and the bills go together (which is still conjecture, to be honest, if the name is common). Why have two things?

Edit: because the decision was to have a strong ID system, so when people show an ID with an address the confidence is high in that being correct.
