Encryption is privacy, as simple as that. 
Privacy should be the default, giving away information should be the exception.
We should never wonder "do I have something to hide, do I have a reason to not give this information?" 
This way of thinking is extremely unhealthy. 
The only real question we should ask ourselves is "do I have a good reason to share this personal information?"
