You are worried about some individual getting access to eMail, when the government already has access to all you communication, text and Mail and Location, guess what they don't need a warrant. Now don't you feel all better.
Then why have any security features at all? If your problem is that the Government can do it, so everyone else can do it, then why even run security features? Why not just leave your phone always unlocked and everything in plain text?
The Government also can enter your home, search it, and leave without your approval or even notifying you; thus using your logic I recommend you leave your house unlocked and the front door open.
