The test site is severely damaged, and they don't have another one. It took what ,6 months to rebuild the launch tower after IFT-1? And it wasn't destroyed, just damaged, on the test site the tanks and pipes and all the rest are right near the vehicle so I see a lot of destruction.

So what, 6 to 9 months while they repair/build new test site(s)?

Might as well cut the losses and scrap Block 2 altogether, and move on to Block 3.
