He may not ever get to Mars, but he's doing something far more important, which is to drastically reduce the cost of putting things into LEO. If he can get it low enough a whole list of things pencil out that weren't economically feasible in the past, like space-based solar power generation.

Without SpaceX it's likely the business would have muddled along without putting any effort into reducing costs for decades.

Yes. The biggest achievement of SpaceX so far was economical and organizational. Musk cleverly employs latest - which are considered common sense in other industries - approaches to the industry known for its conservatism. That gives them - eventually - proverbial kick in the sensitive parts, making them care more.
