The (unproven) target cost per kg of a re-usable starship, from even the most conservative source I could find, was under $300/kg[2]. The next cheapest, the Falcon Heavy, is around $2.3k/kg[1]. The cost difference is astronomical, and so low that it becomes viable send less payload and more orbital adjustment fuel, not to mention its (again, unproven) designed to be refueled in orbit. At that price, you could fly multiple refueling flights and still be under the cost of any other life provider.
