>If you have nothing then Digital IDs won't help you anyway because, if they do include address, you will also need to start by providing a proof of address to the Digital ID system!

The way it works where it works -- you register with municipality and then whenever you need something, they either give a letter with your address (and maybe charge 25 bucks for it) or the agency gets it from the registry maintained by municipality on the need to know basis.

Since the need-to-know basis is set by law, your explicit consent isn't asked for.
