Here is one reason you might block/clear cookies, and be concerned about these issues: If you want to use a Google or Facebook account, but at the same time, you don't want them to be able to link your general browsing history outside of Google/Facebook with your account. ie, the sites you visit and when you visit them. I don't think it's fair to call people with that sort of concern, "paranoid". I think "prudent", "informed" or "sensible" are more appropriate words.
