Cookie banners are not mandated by law, disclosure of and consent to tracking and capturing private user data and its sharing to third parties is. Cookie banners are just the easiest UX pattern to slap on to an existing website, and lends itself to dark patterns so users blindly click "accept all". There's multiple browser extensions that exist that will automatically opt you out and you never have to see those cookie banners again.
