Not particularly no, it's a nice thing to have and it certainly helps as a private citizen, however this is generally confusing anonymity with privacy. I'm comfortable sharing things online because I'm anonymous, because I'd prefer people in my personal life not know about certain things. However I don't keep this information to myself for an illicit benefit, however people don't have a reasonable expectation or justification to know what I'm doing at 10pm on a wednesday night. My boss does have a reason to know what I'm doing at 10am on a Wednesday, in fact he showed up at my job site - didn't concern me, because I wasn't doing anything I shouldn't have been.
However I have a reason and a reasonable expectation to know what my government officials are doing, or at least be able to appoint someone to supervise them. Yet I'm told 'tough shit' because my government for as far as I can see is embezzling my money to areas of government I have no legal rights to even have a trustworthy official even monitor them.
Security Intelligence Services is watchdogged, but why aren't members of my parliament as closely watched as fucking spies! Spies have a lot to hide, and they have justification to hide it, my MP does not have a reason to hide things from me because they got my vote.
