uBlock can't block manual tracking...just third-party scripts that do it.
Example:
You visit example-site.com
example-site.com is the php server that sends you the html. It also the site that does the tracking. So when you click something it sends that data to example-site.com and then it can forward the data to a third-party tracking service.
If you blocked or used host files on the server-side pages then the site example-site.com would be completely blocked too.
Ultimately if everyone uses ad-blocks to block tracking script they can be added to the back end. If you block the back-end you effectively block the website you are accessing in the first place.
