The real complaint from the surveillance police state is that people use encryption for privacy -- whether it's basic communications privacy (end-to-end encrypted text and voice) or basic financial privacy (cryptocurrencies that aren't being made progressively more trackable).

Part of that "used for crime" shit is about things that are against the law just because nobody reported buying a car or something like that, too.

In the real world most encrypted communications is probably people using HTTPS.
