Because in the end the statement that started this whole discussion is still true: we're not there yet, the starship keeps exploding. I have deep respect for SpaceX but what they "explicitly say" doesn't change facts.
We may get there eventually, perhaps even with starship, but the fact remains that in 60 years after Apollo we don't have a comparable heavy rocket.
Wanting F-1 capable engine is like wanting exact recreation of combat performance of F-4. No one involved has cared about that for more than 40 years. Just people who don't understand the tradeoffs so they judge stuff based on silly heuristics.
