Even if it was, I think that everyone's time would always be the same thing in my opinion.

There's no way of speedrunning NDS. It has a set timer so doing it is impossible because everyone would have the same time.

An NDS leaderboard would look something more like a category extensions page, rather than an actual speedrun game page.

He never said to actually complete natural disasters. But yeah those ideas would seem pretty blank and I don't think it would be accepted so easily.

the ideas are bland(told by the creator)
theres no real way to classify if a run is faster or not
and most run would be at the same time
