The flaw in your analogy is that the modal consumer cares about hidden fees, wants to be made aware of them, and might even make a different decision with that knowledge. The modal consumer does not care about cookies.
Imagine you walk into a restaurant and they hand you a paper that details full allergy information for all of the foods they serve, and then they wait for you to say, "I consent to these ingredients being in the food," before they can seat you. I think that's a closer analogy. We can all agree that the restaurant shouldn't hide that information from you, and that some minority of people might want the information, but do we really have to add this inconvenient step to the process for all people? The current real-world system, where allergy information is available upon request, was working fine.
There are some things that everyone cares about and would be appalled by, that businesses should have to inform people about, and many things that a small minority of people care about. Why stop at cookies? Maybe we should mandate a popup if the website's server infrastructure was manufactured abroad, and another popup if the company that runs the website has higher than average carbon emissions, and another popup if the food in the food court that serves the headquarters of the company that runs the website is not kosher. The lobby of people who care about cookies is of similar size to the lobby of people who care deeply about binary size and about running JavaScript. Should there be mandatory popups to execute JavaScript? If the website is >10MB, should I have to consent on a lightweight page before downloading it? How do you determine which activities warrant a popup warning and which do not?
