"IDCAC" doesnt have much to do with privacy, its about convenience. uBO filters dont help you there, as they cant click buttons for you on all the different cookie forms.
If there’s no buttons to worry about clicking (because uBO removed them), what does it matter? GDPR requires you to actively consent, so if you ignore the cookie banner (or block it) advertisers can’t track you.
However it was revealed not long ago that a lot of the third party cookie consent forms used by the majority of sites don't actually have any effect when you interact with them... i.e they tracked everything whether you consented to it or not, I think it was a combination of negligence (incomplete software) and betting on the fact that the vast majority of people just hit accept due to dark patterns that make it extremely inconvenient to do otherwise.
I think using uBlock etc is more likely to result in preventing tracking through blocking known urls and code etc compared to hiding consent forms... I know it's far from infallible but currently most trackers don't bother going to extremes if you block them.
