Yeah it does seem kinda weird. But did you see the SpaceX employees cheering like mad? It’s pretty clear that they think they made a massive step forward today. Are they deluding themselves? They’ve optimized for iteration speed and will have another couple full vehicles ready to go in a month or two. The raptor engines aren’t limited in supply; they’re making 1-2 a day.

My guess is the biggest issue is the destruction of the pad. Building it up so that it doesn’t get destroyed by each launch will be a very expensive challenge.
