Sure, that is true. But given the wide-spread use of banners it is at least obvious that they care enough to ruin their own UX. Which is also a huge cost. As you say, users want a "no and never ask me again". Well, you can have that today. Just don't do anything that requires anyone to say no. And again, if a site chooses that path then the banner is a feature. It is disrespectful and although it is a royal pain it is very good for users to know up front what kind of entity they are dealing with. Remove that and people will become apathetic to it.
