Yup, which is why you pretty much only see them in space applications. Because the weight saved can save enough fuel costs to offset the insane price increases.

I'm not sure how much it costs spaceX with their reusable rockets (and given that Musk is in charge, I would bet that he never did achieve the multiple orders of magnitude cheaper costs he promised), but prior to the space shuttle cost per kg into space was $18,500. After the space shuttle, $54,500/kg.
