Well, let's read this thread and John's thread about ID-cards together.

Most posters in the ID cards thread were against them with more or less good reasons, but a common theme was that the government (or the many governmental agencies) should not know everything about us.

If everybody in any governmental subinstitution would decide following his or her personal prejudices or whims to inform other governmental bodies about what his or her agency has done we would have a situation much worse than with ID cards.

From which age on do you think you would like to inform whoever you think should know about cutting the gas? 65? 70? Or in general?. If I for instance would not pay my gas or electricity bill for whatever reasons (could be a protest, for instance) I would not like to have Social Service at my door next morning. I actually would sue the person who has given them this information.

A doctor informs the police about your diagnosis with cancer? Well, why not, you could contemplate suicide, couldn't you?

Without a very specific reason (child protection e.g.) I see no need to give information about me to anyone who is in no need of this particular information.
