I think you have confused user tracking with site tracking.
Google Analytics is all about tracking what is happening on the site. How many people clicked a particular page. How many people come from a particular region. What are people looking at. What are people looking for. This all helps us make the site better.
Your privacy is not at issue here. We are not tracking you. NoScript does not really help you here as it is set up to protect you from sites/scripts that are tracking you.
