In fact cookie banners show this. People hate them because they force meaningless choices on them. If you make a website with tracking as an opt-out option, almost everyone clicks "accept all". If you make a website with tracking as opt-in, almost every one clicks accept all. That shows that opt-in/out or consent does literally nothing ot reflect people's preferences, the act of making a choice completely dominates the actual decision.
That means that if you want to respect user preferences you don't actually get around making default choices for them, and it's why consent is pretty much meaningless.
