In the old days people had locally installed man pages. Documentation or manuals should be delivered locally by default.
It's handy for when you are traveling and have no mobile internet connection, I've been in the alps where there was no network connection at all. It was very good to have everything I want to lookup (wikipedia, devdocs, cached browser history, epubs, stackoverflow) local.
I can imagine it's handy to maintain focus as well, no internet distraction.
For people who can't affort an network connection it's heaven.
Instead of 'sad and unlucky' I'd say 'smart and lucky'.
