Man, this story is so twisted and convoluted, and the plot so deep, I can't think of any reason why the button is important, except that:
1. Dead Ana Lucia dream visitor and Yeny, dead brother of Mr. Ekko dream visitor, both said it's the most important work. (paraphrased)
2. Yeny might not be Mr. Ekko's brothers name, but that's what came to me. It might be Yani, or Onri or something.
3. Henry showed joy when Locke asked him if he pushed the button or not. Henry's motivation? To make Locke doubt and not press the button.
If something bad does happen, Henry didn't want to be in the hatch when it happened. But he don't mind taking out the hatch if he aint in it.
4. The drawing you can only see with a blue light on the blast door, mentioned the incident. I think the incident really happened, and that the button stops it from happening again.
I think that it's an experiment... to keep them from learning certain things. If they let it go, other things happen, ie; the map on the inner door... the food being dropped.

I think that nothing happens if the button goes unpushed. Well, not to the scale the the Orientation video tells us, anyway. The lights go off, food gets dropped, stuff like that. Not the end of the world or anything.
The Dharma people were experimenting with gene therapy and the like, so it makes sense to me that they would do other shady experiments, like observing what people are willing to do, no matter how irrational it is, when they are afraid.
"Man is a marvelous curiosity ... he thinks he is the Creator's pet ... he even believes the Creator loves him; has a passion for him; sits up nights to admire him; yes and watch over him and keep him out of trouble. He prays to him and thinks He listens. Isn't it a quaint idea." Mark Twain
