I've worked for large media companies where this is exactly the only way to have music available. The production network was blocked from accessing the www. To ensure content wasn't pirated, the original media had to be used. No CD-Rs were allowed. Personal devices were kept in lockers outside the restricted areas, so no streaming from them either.
Email was from a remote session. If you were emailed an attachment necessary for production work, there was an approved workflow to scan the data and then make it available to the production network.
So, while you were trying to be sarcastic, there are networks that are set up exactly like you thought didn't exist because it was too outlandish.
