Well, the government owned physical mail service worked pretty well for a few centuries, so... Not much?

Now, of course, you shouldn't be organizing a criminal conspiracy or in general much anti-government protests over the mail or government-downed email. But the majority of communication is quite benign, and so having a government email for the 80% use case (bills, party invites, holiday wishes, etc) would be great. You can use a separate service for your more sensitive communication.
