I think you've argued directly for the previous poster's point no?
Then of course I looked at flights and it's about 40hrs of travel and $1300 so probably not making that trip in this lifetime.
FYI unlike mainland Norway's national parks, you cannot "randomly" go to the national parks in Svalbard. Svalbard is almost completely devoid of infrastructure (no roads outside the couple of towns) so you'd have to make a completely self-sufficient expedition across arctic terrain to get there. You also need someone with rifle skills in case of a polar bear attack, and it's required to carry a rifle and register all plans with the Governor of Svalbard to leave the town. It's possible, but definitely needs a properly-equipped team -- not a casual trip.

True, I wouldn't want to live there long term -- the limitations of a small town and no road access to other towns could get depressing after a while. But it was definitely an experience being there for a week.
