Oh, its funnier than that. The most sophisticated data trackers don't even use cookies anymore. Anyone you would have to worry about getting that data hasn't used cookies in years. So the entire exercise punishes small companies that don't do anything with the data except pre-populate fields for you. But big tech companies that the law was targeting don't have to change a thing.
But people (like my girlfriend) still click "Allow all" because they don't seem to realize that the legislation requires the website to still function if you decline unnecessary cookies!
The banner is literally an attempt to FOMO you into accepting cookies you never need to accept!
IMO the EU is somewhat in dereliction of Duty for not punishing cookie banner sites
