To clarify, I wasn't saying they were fully self-funding, just giving some additional context to "not that expensive". Given that they have hordes of investors willing to throw money at them (and for decent reason for once), they'd be foolish to significantly slow bootstrapping through the more capex heavy part of the roadmap rather then doing multiple programs at once, particularly when said programs have real synergy. But if for some odd reason they had to go it alone, it's so cheap and F9 beats others so thoroughly that they probably actually could at this point, which is a wild thing to write about super heavy rocket R&D. It'd make everything take many years longer though, and they'd have to prioritize differently.
