Letting trackers track you gives them a lot of information including what pages you visited, some sites can put your email in the url like site.com?email=myemail ... so this trackers will know exactly who you are and what websites you visited. If they fingerprint your browser then they can de-anonymise your private session and will know what you visited in private mode too (this works only for pages that include the respective trackers obviously)

So here is an alternative, browsers will save your private history too, then you go to the website and they will ask for your history, you will have a big button named "Pay with my history and identity", after that you can visit the website without extra JS tracking, in this model all is transparent to the user, you also gain no tracking but you lose the ability to clear your browser history and private mode won't be private.

I personally prefer to block tracking and fingerprinting. When I get the GDPR popup I will close the tab, I don't even try to work around it.
