That's neat.

It is very difficult to do paperwork in France if you don't have a "right" adresse. People often borrow friends adresses when applying for job in a city their don't live in. Student dorms are not considered permanent housing so young people who don't have a family adress notoriously struggle with paperwork. And immigrants face the challenge of breaking the infamous loop "no bank account = no lease, no adress = no bank account".

The adress is considered a part of your identity so it is hard to do without.
