The main loss here isn’t the ship - it’s the pad, LC36. (Which is why SpceX and NASA have separate sites for their static fire tests so their lunch pad and all the GSE isn’t at risk.
Building repairing LC36 will not be quick - SpaceX took 15 months.
The lightning tower is gone. The Transporter-Erector is gone, the GSE is destroyed. The concrete of the pad itself and it’s foundations will have to be repaired if not dug up and replaced before any of the other work can start.
