You have no right to privacy at all, because unless you are Ted Kaczynski, living in a shed on a mountain, modern society requires you to engage with businesses that collect data.
The businesses may collect data, but it’s still illegal for them to sit and read personal aspects of the data unless it has something to do with quality of service or they automatically detect child porn and need to contact authorities.
That’s why you very rarely ever hear of someone (aside from child porno people) getting into legal trouble just by sending emails alone in regards to some sort of other illegal activity. Unless your illegal activity gets exposed some other way, just talking about it with someone isn’t likely to get any attention from a corporation. They could care less and if they made it their business to snoop on their customers even to stop illegal activity it wouldn’t be worth the grief.
If there wasn’t any right to privacy, we’d all be forced to abandon envelopes and use postcards instead. And, opening other people’s envelopes wouldn’t be a federal offense.
That said, I would agree that most email is sent like a postcard nowadays and that needs to stop with much more people using encryption.
