And that is exactly the point. Thank you. What is encoded as compliance in your example is actually the user experience. They off-loaded responsibility completely to the users. Compliance is identical to UX at this point, and they all know it. To modify your sentence: “and most site operators care about focusing on their actual business rather than user experience.”
The other thing is a lack of differentiation. The high penalities you are talking about are for all but of the top traffic website. I agree, it would be insane to play the gamble of removing the banners in that league. But tell me: why has ever single-site- website of a restaurant, fishing club and retro gamer blog a cookie banner? For what reason? They won’t making a turnover you dream about in your example even if they would win the lottery, twice.
