Lots of them up there? I would think that one would want an insider due to the extended length of the winter.
Alaskans are tough. 40 below? Moose curled up in front of the outhouse? Squirrel ate the paper again? Got to be tough to survive. Raw nature has a way of forcing one to confront reality. You might not have to be exactly sane to be in Alaska, but you have to be functional.
Lack of electricty and running water creates the need for lots of Outhouses. It is the "Last Frontier" ya know.
