The world existed before you. So... You can't just come and say the concept of passport is archaic, the concept of countries is archaic, the concept of nationalities is archaic, the concept of government is archaic, the concept of birth certificates is archaic (yes, people collected your data before you agreed and became aware). France is the country of the french people who have their culture (that word includes a lot of things), and those people want to decide who they want to see on their territory. So you can't just come to the world naively thinking that you can go wherever you want. And legal system (another archaic concept) is the reason that you can. Otherwise, you would probably end up just like your cat when it ventures into neighbors backyard.
