"Who has no internet for more than three days?"
...People on vacation. (People who have gone somewhere remote for vacation and have brought their laptop so they can work on their novel or their game dev without distractions.) People who live in a place where internet is unavailable or unreliable, and they go to the library once in a while to download things. People whose only internet is their phone, and sure, it has a hotspot, but they can't afford to use it regularly. Kids whose parents strictly regulate their internet access. Kids in boarding schools that strictly regulate internet access. People whose internet service was lost after a natural disaster, and it'll probably be fixed in a week or two but in the meantime, they have computers, just no online ability - and they're desperately interested in playing the games they have.
