Do you have a google, yahoo, AOL, MSN, hotmail, or other nonencrypted email service? Most entities keep archives of significant amounts of info you share, even privately through email. The US government has a right to view that data if they have “reasonable suspicion” of any crime.

They have decided that they will begin offering email!! Why does that matter? If the government asks to see a particular account they will get encrypted data. To be sure, it’s possible to de-encrypt this kind of stuff, but not in all circumstances, and it is extremely difficult. If you couple that with an account paid for in Bitcoin and Tor or some other onion browser the ability to link an identity to actions done online is exponentially decreased.
