Cookie banners are just a kind of ad. If you're at the site, the demand you have for the content on the site is probably close to inelastic (especially on services websites). The site exploits its effective monopoly on the content to raise prices to the user (in this case your time, attention, and experience).

There is ZERO cost to abusing the user over, and over, and over again by asking for permission to track them.

We shouldn't have the cookie banners at all because NO company should be able to do anything with tracking data. Just ban the use of user data by companies and most of SillyCon Valley's garbage behaviors are fixed.

Similarly, I should never get "terms of service updates" from digital companies because there should be no changes that they can make. You can provide the obvious service that you're providing; you can't aggregate my data for any purpose other than directly serving me; you can't aggregate my data with that of other users; if you retain my data for any other purpose, the government should take percentages of your revenue. I shouldn't have to wade through the BS that the mercenary corporate lawyers cook up to extract value from me.
