Aha, I get it. And that's indeed the problem, you have to consent to the cookies or you can't use the site. So everybody just clicks "Agree" automatically when these annoying pop-ups appear.
Even bigger problem is, cookie tracking was the main thing 10 years ago, but now they have so much more sophisticated tracking methods available, and they're all on the hosting servers, not on your local device. There are servers that track every webiste you visit and track every click on every link you make. And then the buggers sell this data off to other buggers.
