By enabling entirely new applications that aren't remotely economical otherwise. Asteroid mining, orbital manufacturing, all that scifi stuff that we've been talking about for half a century and can't do at thousands of dollars per pound to LEO. Cheap high-volume launch means you can build things heavier and in some cases mass-produce them, so space hardware doesn't have to cost so much anymore either.
