Your "logic" is baffling
That is what I meant by "practically". I mean "in a practical sense" as opposed to in a theoretical sense.
That literally does not happen. What world do you live in?
But just to entertain your scenario let's say that did happen: it still wouldn't matter because they could just reply and tell them why they don't need one...
For regulators in general doing dumb things? Lots and lots of examples all over the place. Talk to any small-business owners you know, get them drunk, and encourage them to rant. You'll hear some stories.
So, cookie banner it is.
Individuals and other businesses have to complain to regulators about others not complying with the GDPR.
This is how you minimize headaches and your legal bill. And on the day that people come after you for some unforeseeable tragedy or perhaps genuine wrongdoing (covered up by unscrupulous employees or less-than-honest vendors), you'll be better positioned to deflect legal repercussions and bad press.
The unnecessary cookie banner is a no-brainer: it costs you nothing and poses but a minimal irritant to users.
