Why do people care who Satoshi Nakamoto is/was? It's like wondering the name of the person that created the wheel. Sure, I suppose I would be curious about the name of the inventor of the wheel, if nothing else to raise a beer to them from time to time, but ultimately the wheel is the important part of the story.
More a case of curiosity, I believe. A mythical figure creating the thing, given to devs, then gone. Very romantic way of seeing it, gift to the world. Quite possibly the ingenious thing was to remain anonymous, making Bitcoin faceless (everyone's coin)
