You don't need cookie banners unless you want to track the user before they opted in on their own (maybe in the "website settings"). That's why countless websites have none.

The browser would only have to ask once, and then it would still just be "one browser setting", except you'd be notified it exists, as soon as it exits. So what's the point here, other than trotting out the same old stuff nut about cookie banners?

On update, "this is the thing, and that thing is enabled by default, is that okay? Otherwise, click no, then it gets turned off. If you change your mind later, it's under settings -> thing"

It's not complicated, and blaming laws that enforce human rights to avoid the most basic craftsmanship is suspicious.
