An interesting thing here is SpaceX are building TWO launchpads. Which will definitely help prevent delays if an when there is an AMOS-6 [1] or Orb-3 [2] type explosion that destroys the launchpad.
It may also help for rapidly testing orbital refueling in 2022, though the plan is to do orbital refueling with 1 launch pad, 1 Super Heavy and 2 Starships (1 standard, 1 refueler) with 1 hour turnaround times between launches (and 5-6 launches) before Starship is ready to depart for the journey to Mars.
