They gave up on reusability post shuttle / now with SLS and in fact are producing a new version that’s cheaper that forgoes any attempt at reuse.

A fully & rapidly reusable orbital rocket is fundamental to extending life beyond Earth. Propellant cost is roughly a 1000th of vehicle cost (unless using a foolish propellant). Same principle as cars, planes, boats, etc.
