I mean, iirc in the USA the postal service is a consitutionally mandated service. So this could be (legally) done "overnight" simply by defining electronic mail sevice as a form of postal service. Plus that would be an email service subject to the privacy protections of the USPS.

USPS “privacy?” Lol.

Agreed. Though to be clear, I meant legal right to privacy, not necessarily in practice. The USPS cannot legally open mail without a warrant, whereas any LEO can legally just ask google for access to your emails and google can legally just give it to them.
