It's incredible that we live in a world where a statement like this has at least some veracity.
I was following starship from the time when was still called ITS or BFR.
As for the not adequate launch site infrastructure that had 0 to do with the date, they built the pad long before launch, expecting the fondag to handle the heat/pressure and it didn't work, they didn't suddenly build a pad throw it together and say we're launching cause 4/20 because LOL.
I have great news for you, they have already done that!

Forgive me if I'm not going to click on a Twitter link, but the YouTube video only covers site infrastructure. I see no evidence that Elon won't Elon again. 4/20 blaze it.
If Elon didn't want things to be delayed so bad by the FAA maybe he shouldn't have launched on 4/20 for the lulz without adequate launch site infrastructure for such a launch.
The FAA shouldn't let them launch until SpaceX has proven they've done the work and have done their best to mitigate these issues going forward - both the actual consequences and the decision processes that led to them. From what I remember the FAA basically rubber stamped SpaceX's incident report (or whatever it was called) that the Internet reported as being from the FAA itself.
