his logic... well, as expected of someone who ran away from real life to build houses. I get that the salaryman atmosphere in Japan isn't exactly something an average person can change (understatement of the year), but if your point of analysis is that "well you didn't go overboard in your request so you're better" then tragedy of the commons is lurking right around the corner.
Sooner or later, the un-handled quests are going to develop into an issue, and sooner or later someone's gonna have to handle it. So it's an incomplete analysis no matter how you put it- life doesn't wait for you to get all your eggs into a neat little row, so even that "reliability" is based largely on luck.
