If the rule was applied literally and strictly, that would be even better. Is consent given by agreeing to a huge banner that pops up anew every time you load the page? Fine, you can do that, but then you have to pop up a huge "withdraw consent" banner every time a user that gave consent visits your site. Which you probably don't want, so you can't do the obnoxious opt-in banner either. In practice, that would make any obnoxious way to ask for consent untenable, because you couldn't use it to annoy users into consenting (and staying in consenting state).
