But, yes, different societies have different approaches there and they are kind of designed around it.
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!
> And proof of address is not a utility bill there, but either a form from your landlord or land register.
Because you've decided to do that, not because there is a practical requirement, which is my point.
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.
