Privacy is hard because the definition of privacy differs depending on who you ask to. And people think companies have your data, so "what's the point?".
Data economy which survives on privacy encroaching practices depend on ur "stream of data". Reducing the flow can exclude you from data breaches, spam calls, personalised pricing which rips from you etc.
Sure, there are PII which can't be hidden. But you surely can reduce the footprint. And browsing the internet is always a better UX with adblockers.
