owners will easily circumvent it and raise dangerous dogs that are that breed or essentially are.

French laws banned a hand full of breeds entirely, and heavily restricted a whole host of others, specifically including all breeds that look like the banned ones. If you want a category 2 dog, it needs to be registered, insured, you need to show yourself capable and it need to be muzzled at all time in public.

You can’t just “get a similar dog”, because that’s also restricted. Not that this guy would ever clear the legal requirements anyway.
